(A) 5 and 7
(B) 0 and 1
(C) 5 and 6
(D) 6 and 7
(B) 0 and 1
A fraction whose numerator(N) is less than the denominator(D) is called a proper fraction.
So, 5/7 = 0.715
Therefore, 5/7 lies between 0 and 1.
Question 9.
Write down the 11 natural numbers from 2 to 12. What fraction of them are prime numbers?
Natural numbers from 2 to 12 are – 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.
Prime numbers from among these numbers are 2, 3, 5, 7, and 11.
Therefore, out of the 11 numbers, 5 are prime numbers. It represents a fraction of 5/11.
Question 10.
Write the 12 natural numbers from 102 to 113. What fraction of them are prime numbers?
Natural numbers from 102 to 113 are – 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113
Among these 12 numbers, the 4 prime numbers are 103, 107, 109, and 113.
Therefore, out of the 12 numbers, 4 are prime numbers. It represents a fraction of 4/12.
Question 11. When ¼ is written with the denominator as 12, its numerator is
(1 × 3)/(4 × 3) = 3/12
Consider, 3/12
Divide both numerator and denominator by 3.
Question 12. Which of the following fraction is not equal to the others?
(ii) 12/16

All the options given in the question are further simplified as follows,
Divide both numerator and denominator by 2.
Divide both numerator and denominator by 4.
Divide both numerator and denominator by 5.
Divide both numerator and denominator by 6.
Comparing all results, (¾ = ¾ = ¾) ≠ 3/5
Therefore, (6/8 = 12/16 = 18/24) ≠ 15/25
Question 13. Which of the following given fractions is the greatest?
We know that among all fractions with the same numerator, the one having a smaller denominator will be the highest fraction.
5/9 < 5/8 < 5/7 < 5/6
Therefore, among four options, (ii) 5/6 has a small denominator. So, it is the greatest fraction.
Question 14. The mixed fraction 5(4/7) can also be expressed as –
(iii) 33/4
The mixed fraction 5(4/7) can be expressed as = 5 + (4/7)
= (35 + 4)/7
Question 15. Is 7/19 a fraction?
7/19 is a proper fraction.
Question 16. Are 5/8 and 3/8 proper fractions or not?
5/8 and 3/8 are like proper fractions.
Fractions with the same denominators are called fractions.
Question 17. What type of fractions are 18/135 and 90/675. Are they proper, unlike fractions?
18/135 and 90/675 are proper, unlike and equivalent fractions.
Consider the two given fractions, 18/135 and 90/675
So, (18/135) = (90/675)
By cross multiplication, we get
(18 × 675) = (90 × 135)
12,150 = 12,150
Therefore, 18/135 and 90/675 are proper, unlike and equivalent fractions.
Question 18. The following fractions below are represented by just three different numbers. Now, separate them into three groups of all equivalent fractions by changing each one of them to its simplest form.
(i) 2/12 (ii) 3/15 (iii) 8/50 (iv) 16/100 (v) 10/60 (vi) 15/75
(vii) 12/60 (viii) 16 / 96 (ix) 12 / 75 (x) 12 / 72 (xi) 3 / 18 (xii) 4/25
(i) 2 / 12 = (1 × 2) / (6 × 2)
(ii) 3 / 15 = (1 × 3) / (5 × 3)
(iii) 8 / 50 = (4 × 2) / (25 × 2)
(iv) 16 / 100 = (4 × 4) / (25 × 4)
(v) 10 / 60 = (1 × 10) / (6 × 10)
(vi) 15 / 75 = (1 × 15) / (5 × 15)
(vii) 12 / 60 = (1 × 12) / (5 × 12)
(viii) 16 / 96
= (1 × 16) / (6 × 16)
(ix) 12 / 75 = (4 × 3) / (25 × 3)
(x) 12 / 72 = (1 × 12) / 6 × 12)
(xi) 3 / 18 = (1 × 3) / (6 × 3)
(xii) 4 / 25
Totally there are three groups of equivalent fractions.
1 / 6 = (a), (e), (h), (j), (k)
1 / 5 = (b), (f), (g)
4 / 25 = (c), (d), (i), (l)
Question 19. Find the answers to the following. Write and indicate how to solve the following:
(a) Is 5 / 9 equals(=) to 4 / 5
(b) Is 9 / 16 equals(=) to 5 / 9
(c) Is 4 /5 equals(=) to 16 / 20
(d) Is 1 / 15 equals(=) to 4 / 30
(a) 5 / 9 and 4 / 5
Now, convert all these fractions into like fractions:
5 / 9 = (5 / 9) × (5 / 5)
4 / 5 = (4 / 5) × (9 / 9)
∴ 25 / 45 ≠ 36 / 45
Therefore, 5 / 9 is not equal to 4 / 5
(b) 9 / 16, 5 / 9
Convert all these fractions into like fractions:
9 / 16 = (9 / 16) × (9 / 9)
5 / 9 = (5 / 9) × (16 / 16)
∴ 81 / 144 ≠ 80 / 144
Therefore, 9 / 16 is not equal to 5 / 9
(c) 4 / 5, 16 / 20
16 / 20 = (4 × 4) / (5 × 4)
∴ 4 / 5 = 16 / 20
Therefore, 4 / 5 is equal to 16 / 20
(d) 1 / 15, 4 / 30
4 / 30 = (2 × 2) / (15 × 2)
∴ 1 / 15 ≠ 4 / 30
Therefore, 1 / 15 is not equal to 4 / 30.
Question 20. Rafiq had exercised for 3 / 6 of an hour today, while Rohit exercised for 3 / 4 of an hour today. Who exercised for a longer ime today?
Rafiq exercised = 3 / 6 of an hour
Rohit exercised = 3 / 4 of an hour.
3 / 6 and 3 / 4
Convert both of these into like fractions:
(1) 3 / 6 = (3 × 2) / (6 × 2) = 6 / 12
(2) 3 / 4 = (3 × 3) / (4 × 3) = 9 / 12
So clearly, 9 / 12 is greater than 6 / 12.
∴ 3 / 4 > 3 / 6
Hence, Rohit exercised for a longer time than Rafiq.
Question 21 . In class A of total 25 students, 20 passed with 60% or more marks; in class B, of total 30 students, 24 passed with 60% or re marks. Calculate in which class was a greater fraction of students getting 60% or more marks.
The total number of students in Class A = 25
Students passed in the first class in Class A = 20
Therefore, fraction = 20 / 25
The total number of students in Class B = 30
Students passed in the first class in Class B = 24
Therefore, fraction = 24 / 30
∴ An equal fraction of the students passed in first class in both classes
Question 22.
Write all these fractions appropriately as additions or subtractions:
(a) The total number of parts each rectangle has = 5
No. of all shaded parts in first rectangle = 1 i.e 1 / 5
No. of all shaded parts in second rectangle = 2 i.e 2 / 5
No. of all shaded parts in third rectangle = 3, i.e. 3 / 5
Clearly, the fraction which is represented by the third rectangle = the sum of the fractions represented by the first and the second rectangle.
Therefore, 1 / 5 + 2 / 5 = 3 / 5
(b) The total number of all parts each circle has is = 5
We have observed that the first, second and third circles represent 5, 3 and 2 shaded parts out of total 5 equal parts, respectively. Clearly, the Fraction represented above by the third circle is the difference between the fractions represented by the first and second circles.
Hence, 5 / 5 – 3 / 5 = 2 / 5
(c) Here, we may observe that the first, second and third rectangles represent 2, 3 and 5 shaded parts out of 6 equal parts, respectively. Clearly, the fraction represented by the third rectangle is the sum of fractions represented by the first and second rectangles.
Hence, 2 / 6 + 3 / 6 = 5 / 6
Question 23.
Kristin had received a CD player for her birthday. She bought 3 CDs and received five others as a gift. What fraction of the total CDs did she buy, and what fraction did she receive as gifts?
Answer 23. Total number of CDs with Kristin = 3 + 5
Total number of CDs she bought = 3
CDs she received as gift = 5
fraction of CDs she bought = 3/8
fraction of CDs she received as gift = 5/8
Question 24.
Ramesh had 20 pencils, whereas Sheelu had 50 pencils, and Jamaal had 80 pencils. After four months, Ramesh used up ten pencils, Sheelu also used up 25 pencils, and Jamaal also used up 40 pencils. What fraction did each of them use up? Check if each of them has used up an equal fraction of her/his pencils.
Fraction used by Ramesh = 10/20 =1/2
Fraction used by Sheelu = 25/50 = 1/2
Fraction used by Jamaal = 40/80 = 1/2
Yes, all of them used an equal fraction of pencils, i.e., 1/2.
Question 25.
Write the fractions and pair up with the equivalent fractions from each row.
(a) Here, 1 part is shaded out of total of 2 equal parts (i.e., rectangle). Hence, this figure represents a fraction 1/2.
(b) Here, four parts are shaded out of 6 equal parts (i.e., rectangle). Hence, this figure represents a fraction of 4/6 = 2/3.
(c) Here, three parts are shaded out of 9 equal parts (i.e., squares). Hence, this figure represents a fraction of 3/9 = 1/3.
(d) Here, two parts are shaded out of 8 equal parts (i.e., rectangle). Hence, this figure represents a fraction of 2/8 = 1/4.
(e) Here, three parts are shaded out of 4 equal parts (i.e., squares). Hence, this figure represents a fraction of 3/4.
(i) Here, six parts are shaded out of 18 equal parts (i.e., triangles). Hence, this figure represents a fraction of 6/18 = 1/3.
(ii) Here, four parts are shaded out of 8 equal parts (i.e., rectangles). Hence, this figure represents a fraction of 4/8 = 1/2.
(iii) Here, 12 parts are shaded out of total of 16 equal parts (i.e., squares). Hence, this figure represents a fraction of 12/16 = 3/4.
(iv) Here, eight parts are shaded out of 12 equal parts (i.e., rectangles). Hence, this figure represents a fraction of 8/12 = 2/3.
(v) Here, four parts are shaded out of 16 equal parts (i.e., triangles). Hence, this figure represents a fraction of 4/16 = 1/4.
Now, these figures above can be matched correctly as
(a)-(ii), (b)-(iv), (c)-(i), (d)-(v), (e)-(iii)
Question 26.
Fill in the blanks:
There is a large box of 36 small square boxes.
= 36/2 = 18 boxes.
2/3rd of 36 is equal to 24
So, if i make a bench of 20 small boxes, the fraction becomes 5/9
x = (36×5)÷6
So, 30 boxes are required for the fraction to be 5/6
Question 27. Solve:
(a) 1 / 18 + 1 / 18
(b) 8 / 15 + 3 / 15
(c) 7 / 7 – 5 / 7
(d) 1 / 22 + 21 / 22
(e) 12 / 15 – 7 / 15
(f) 5 / 8 + 3 / 8
(g) 1 – 2 / 3 (1 = 3 / 3)
(h) 1 / 4 + 0 / 4
(i) 3 – 12 / 5
= (1 + 1) / 18
= (8 + 3) / 15
= (7 – 5) / 7
= (1 + 21) / 22
(e) 12 /15 – 7 / 15
= (12 – 7) / 15
= (5 + 3) / 8
(g) 1 – 2 / 3
= 3 / 3 – 2 / 3
= (3 – 2) / 3
(h) 1 / 4 + 0
= 15 / 5 – 12/ 5
= (15 – 12) / 5
Question 28. Shubham had painted 2 / 3 of the wall space in his room. His sister Madhavi had helped and painted 1 / 3 of the wall space. How much did they paint together?
Wall space painted by Shubham in a room = 2 / 3
Wall space painted by Madhavi in a room = 1 / 3
Total space painted by both = (2 / 3 + 1 / 3)
= (2 + 1) / 3
∴ Shubham and Madhavi together painted one complete wall in a room.
Question 29. Nandini’s house is about 9 / 10 km from her school. She walked some distance towards her school and then took a bus for 1 / 2 km to reach the school. How far did she walk?
Distance of the school from house = 9 / 10 km
The distance she travelled by bus = 1 / 2 km.
Distance walked by Nandini = Total distance of the school – Distance she travelled by bus.
= 9 / 10 – 1 / 2
= [(9 × 1) – (1 × 5)] / 10
= (9 – 5) / 10
∴ The distance walked by Nandini is 2 / 5 km.
Question 30. Asha and Samuel had bookshelves of the same size, partly filled with books. Asha’s shelf is 5 / 6th full, and Samuel’s shelf is 2/ 5 th full. Whose bookshelf is more full? By what fraction?
Fraction of Asha’s bookshelf = 5 / 6
Fraction of Samuel’s bookshelf = 2 / 5
Convert these fractions into like fractions
5 / 6 = 5 / 6 × 5 / 5
= (5 × 5) / (6 × 5)
2 / 5 = 2 / 5 × 6 / 6
= (2 × 6) / (5 × 6)
25 / 30 > 12 / 30
5 / 6 > 2 / 5
∴ Asha’s bookshelf is little more full than Samuel’s bookshelf.
Difference = 5 / 6 – 2 / 5
= 25 / 30 – 12 / 30
Question 31. Jaidev takes around minutes to walk across the school ground. Rahul takes around 7 / 4 minutes to do the same. Who takes lesser time, and by what fraction?
Time is taken by Jaidev to walk across the school ground =
= 11 / 5 minutes
The time it took for Rahul to walk across the school ground = was 7 / 4 minutes.
11 / 5 = 11 / 5 × 4 / 4
= (11 × 4) / (5 × 4)
7 / 4 = 7 / 4 × 5 / 5
= (7 × 5) / (4 × 5)
Clearly, 44 / 20 > 35 / 20
11 / 5 > 7 / 4
∴ Rahul takes lesser time than Jaidev to walk across the school ground.
Difference = 11 / 5 – 7 / 4
= 44 / 20 – 35 / 20
Hence, Rahul walks across the school ground for 9 / 20 minutes.
Question 32. A small piece of wire 7 / 8 metre long broke into two pieces. One piece is 1 / 4 metre long. How long is the other piece?
Total length of the wire = 7 / 8 metre
Length of one piece of the wire = 1 / 4 metre
Length of another piece of the wire = Length of the original wire, and this one piece of wire
= 7 / 8 – 1 / 4
= [(7 × 1) – (1 × 2)] / 8
= (7 – 2) / 8
∴ Length of the other piece of the wire = 5 / 8 metre
Question 33. Sarita bought 2 / 5 metres of ribbon and Lalita 3 /4 metres of the ribbon. What is the total length of the ribbon that they bought?
Length of the ribbon bought by Sarita = 2 / 5 metre
Length of the ribbon bought by Lalita = 3 / 4 metre
Total length of the ribbon bought by two of them = 2 / 5 + 3 / 4
Taking LCM 20
= [(2 × 4) + (3 × 5)] / 20
= (8 + 15) / 20
= 23 / 20 metre
∴ The total length of the ribbon that was bought by both Sarita and Lalita is 23 / 20 metres.

Then the fractions will be
$ \dfrac{2\times 20,3\times 30,7\times 12,8\times 8,5\times 15}{120} $
$ =\dfrac{80,90,84,64,75}{120}$
$=\dfrac{80}{120},\dfrac{90}{120},\dfrac{84}{120},\dfrac{64}{120},\dfrac{75}{120} $
Ascending order will be

$ =\dfrac{8}{15},\dfrac{5}{8},\dfrac{2}{5},\dfrac{7}{10},\dfrac{3}{4} $
Descending order will be
$=\dfrac{90}{120},\dfrac{84}{120},\dfrac{80}{120},\dfrac{75}{120},\dfrac{64}{120} $
$ =\dfrac{3}{4},\dfrac{7}{10},\dfrac{2}{3},\dfrac{5}{8},\dfrac{8}{15} $
A fraction is a number that represents a part of a whole number. Fractions represent equal parts of a whole or a collection.
A fraction is represented by two parts separated by the “/” symbol. The number written above the line is called the numerator. It helps us to know how many equal parts of the whole or collection are taken. The number written below the line is known as the denominator. With the help of fraction, we can know the total number of equal parts which are there in a collection.
Proper fractions
Improper fractions
Mixed fractions
Like fractions
Unlike fractions
Equivalent fractions
The proper fractions are those fractions where the numerator is less than the denominator.
Example: 5/9 will be a proper fraction since “numerator < denominator”.
The improper fraction is a fraction where the numerator is greater than the denominator.
Example: 9/5 will be an improper fraction since “denominator < numerator”.
The combination of the integer part and a proper fraction is called a mixed fraction also known as a mixed number.
Example: \[3\frac{1}{2} = \frac{(3 \times 2) + 1}{2} = \frac{7}{2}\]
Like fractions are a fraction that has two or more fractions that have the same denominator. Example- Take ½ and 2/4, they are alike fractions since if we simplify it mathematically, we will get the same fraction.
Unlike fractions are fractions that have different denominators.
Example: ½ and ⅓ are unlike fractions.
Two fractions are said to be equivalent to each other if after simplification either of two fractions is equal to the other one.
Example: ⅔ and 4/6 are equivalent fractions.
Since, 4/6 = (2 × 2)/(2 × 3) = ⅔

There are some basic rules we should know before solving the problems based on fractions.
Before performing addition or subtraction on fractions, we must make sure that the denominators are equal. Hence, addition and subtraction of fractions are possible only when the denominator is common.
If we have multiplied two fractions, then the numerators are multiplied as well as the denominators are multiplied. Later, simplify the fraction.
When we divide a fraction from another fraction, we need to find the reciprocal of the other fraction and then multiply it to the first one to get the answer.
The addition of fractions is easy when they have a common denominator, we need to just add the numerators here.
Example: ⅔ + 8/3 = (2 + 8)/3 = 10/3
If the denominators of the two fractions are different then we have to simplify them by finding the LCM of denominators and then making it common for both fractions.
Example: ⅔ + ¾
Here, the denominators are 3 and 4.
Hence, LCM of 3 and 4 is 12.
Therefore, we multiply ⅔ by 4/4 and ¾ by 3/3, we get,
= 8/12 + 9/12
= (8 + 9)/12
The rule for subtracting two or more fractions is the same as for addition. We should make denominators common to subtract two fractions.
Example: 9/2 – 7/2 = (9-7)/2 = 2/2 = 1
If the denominators of the two fractions are different, then we have to simplify them by finding the LCM of denominators after that making it common for both fractions.
For example ⅔ – ¾
8/12 – 9/12
= (8 – 9)/12
As per rule 2, when two fractions are multiplied, then the top part (numerators) and the bottom part (denominators) are multiplied together.
Suppose a/b and c/d are two different fractions, then the multiplication of a/b and c/d will be:
(a/b) × (c/d) = (a × c)/(b × d) = (ac/bd)
Example: Multiply ⅔ and 3/7.
= (⅔) × (3/7) = (2 × 3)/(3 × 7) = 2/7
As per rule 3, if we have to divide any two fractions where we need to multiply the first fraction to the reciprocal of the second fraction.
Suppose, a/b and c/d are two different fractions, then the division a/b by c/d can be expressed as:
(a/b) ÷ (c/d) = (a/b) × (d/c) = (ad/bc)
Example: Divide ⅔ by 3/7.
(⅔) ÷ (3/7) = (⅔) × (7/3) = (2 × 7)/(3 × 3) = 14/9

1. What is a fraction Class 6?
A fraction is a part of the whole. It is a numerical quantity which is not whole. Fractional numbers are used to represent a part of something. Some examples of fractions could be one-third, three-fourth etc. A fraction is described in the form of p/q. The letter p expresses the numerator of the fraction whereas the letter q expresses the denominator of the fraction. In a fraction 3/8, 3 is the numerator and 8 is the denominator. It represents 3 portions of the 8.
2. What are types of fractions?
The chapter introduces you to the concept of fraction. The chapter explains five types of fractions, namely, proper fractions, improper fractions, mixed fractions, like fractions and unlike fractions. Proper fraction is when the denominator is greater than the numerator. Improper is when the denominator is less than a numerator. Mixed fractions are those which consist of a whole number and a fraction. Two fractions are called when they have the same denominators. Two fractions are unlike fractions if they have different denominators.
3. Do whole numbers also have denominators?
Fractions are numbers expressed in the form of p/q. If a number can be expressed in the p/q form, it is called a fraction. Whole numbers are those numbers that can be drawn on a number line. It is possible to write whole numbers in the form of p/q. Numbers that are whole have the denominator 1. So, a number as 3 can also be written as 3/1, where 3 is the numerator and 1 is the denominator. Writing a whole number in the fraction form helps in our calculation immensely.
4. What fraction of a day is 8 hours?
A day has 24 hours. So, 24 will be the denominator that represents the whole. When we want to find a fraction of 8 hours, 8 will be our nominator. So, our fraction will be 8/24. What we are trying to find will come in the place of numerator and what we already know will come in the place of denominator. 8 and 24 are both divisible by 8, so we can simplify the fraction by dividing both numerator and denominator by 8. 8/8 will give us 1, which will be our new numerator. 24/8 will give us 3, our new denominator. So, our new fraction will be the new numerator/new denominator. Our answer is ⅓. 8 hours is one-third of 24 hours.
5. What is the difference between proper and improper fractions?
A fraction consists of a numerator and a denominator. A number that occupies the place above the line is the numerator. The number that occupies the bottom is the denominator. A proper fraction is one in which the denominator is greater than the numerator. For example, 4/7 (7 is greater than 4), 3/11 (11 is greater than 3). However, if the numerator is greater than the denominator, then the fraction is called an improper fraction. For example, 8/7 and 13/6 where 8 and 13 are greater than 7 and 6 respectively.

Fractions
We all have heard of this word in the field of mathematics as well as in our everyday lives. For example when we divide a chocolate in two pieces, it is a fraction. When we eat half of an apple it’s a fraction. In mathematics fraction plays a very important role and let’s find out how?
Understanding Fractions
A fraction consists of two parts:
Thus a number is written above and a below the horizontal line and then the arrangement is called as fraction.
Types of Fractions
There are three types of fractions
Example 2 : 1/4, 5/8, 3/5, 4/7, etc.
Example 3 : 5/2, 7/4, 9/7, 13/11, 2/2, etc.
Example 4 : Convert the fraction 17/4 in mixed fraction.
Example 5 : Solve the above example.
Solution : To solve this we will follow 3 steps
(6 +1 = 7).
Hence the fraction becomes 7/3 which is an improper fraction.
There is another category of fractions called as
Equivalent Fractions : Those fractions which look different but on solving become same.
Like and Unlike Fractions
Fractions with same denominators are called like fractions . For example 2/3, 4/3, 5/3 etc are all like fractions.
Fractions which don’t have same denominators are called as Unlike Fractions . For example, 2/5, 4/7, ½, etc. is unlike fractions
Comparing Fractions
Comparing means to find out some characteristics like which one is smaller and which is greater when two or more numbers are observed together which means compared together.
Here we are going to compare two fractions whose denominators are same that is they are like fractions.
Now observe the numerator, the fraction whose numerator is greater will be the greater fraction.
Example 7 : Compare who is greater 6/7 or 5/7.
Solution : Here both the fractions have the same denominator and hence on observing the numerators we get that 6 is greater than 5 there 6/7 is greater than 5/7.
When we have to compare two fractions which don’t have same denominators that is they are unlike fractions then we will compare them in the following manner:
Computing operations on fractions
As we all know that addition, subtraction, multiplication and division are the computing operations.
Here we are going to study only the first two computation operations on fractions.
Addition and Subtraction of Fractions
Two fractions with the same denominator can be added or subtracted by using the two steps :
Example 8 : Add and subtract 4/5 and 3/5.
Solution : As we can see the denominators of both the fractions is same and hence we can add and subtract them by using the numerators .
Therefore, 4/5 + 3/5 = 7/5 and 4/5 – 3/5 = 1/5.
Practice Questions
Question 1 : Write the natural numbers from 102 to 113. What fraction of them are prime numbers?
Question 2 : Which one is smaller 1/13 or 13/13?
Question 3 : Solve the mixed fraction 5 ½.
Question 4 : State True or False:

1 / 5 = (b), (f), (g)
4 / 25 = (c), (d), (i), (l)
7. Find answers to the following. Write and indicate how you solved them.
(a) Is 5 / 9 equal to 4 / 5?
(b) Is 9 / 16 equal to 5 / 9?
(c) Is 4 /5 equal to 16 / 20?
(d) Is 1 / 15 equal to 4 / 30?
(a) 5 / 9, 4 / 5
Convert these fractions into like fractions
5 / 9 = (5 / 9) × (5 / 5)
4 / 5 = (4 / 5) × (9 / 9)
∴ 25 / 45 ≠ 36 / 45
Hence, 5 / 9 is not equal to 4 / 5
(b) 9 / 16, 5 / 9
Convert into like fractions
9 / 16 = (9 / 16) × (9 / 9)
5 / 9 = (5 / 9) × (16 / 16)
∴ 81 / 144 ≠ 80 / 144
Hence, 9 / 16 is not equal to 5 / 9
(c) 4 / 5, 16 / 20
16 / 20 = (4 × 4) / (5 × 4)
∴ 4 / 5 = 16 / 20
Hence, 4 / 5 is equal to 16 / 20
(d) 1 / 15, 4 / 30
4 / 30 = (2 × 2) / (15 × 2)
∴ 1 / 15 ≠ 4 / 30
Hence, 1 / 15 is not equal to 4 / 30
8. Ila read 25 pages of a book containing 100 pages. Lalita read 2 / 5 of the same book. Who read less?
Total number of pages a book has = 100 pages
Lalita read = 2 / 5 × 100 = 40 pages
Ila read = 25 pages
∴ Ila read less than Lalita.
9. Rafiq exercised for 3 / 6 of an hour, while Rohit exercised for 3 / 4 of an hour. Who exercised for a longer time?
Rafiq exercised = 3 / 6 of an hour
Rohit exercised = 3 / 4 of a hour
3 / 6, 3 / 4
Convert these into like fractions
3 / 6 = (3 × 2) / (6 × 2)
3 / 4 = (3 × 3) / (4 × 3)
Clearly, 9 / 12 > 6 / 12
∴ 3 / 4 > 3 / 6
Therefore Rohit exercised for a longer time than Rafiq.
10. In a class A of 25 students, 20 passed with 60% or more marks; in another class B of 30 students, 24 passed with 60% or more marks. In which class was a greater fraction of students getting with 60% or more marks?
Total number of students in Class A = 25
Students passed in first class in Class A = 20
Hence, fraction = 20 / 25
Total number of students in Class B = 30
Students passed in first class in Class B = 24
Hence, fraction = 24 / 30
∴ An equal fraction of students passed in first class in both the classes
Exercise 7.5 page no: 157
1. Write these fractions appropriately as additions or subtractions:
(a) Total number of parts each rectangle has = 5
No. of shaded parts in the first rectangle = 1 i.e 1 / 5
No. of shaded parts in the second rectangle = 2 i.e 2 / 5
No. of shaded parts in the third rectangle = 3 i.e 3 / 5
Clearly, the fraction represented by the third rectangle = Sum of the fractions represented by first and second rectangle
Hence, 1 / 5 + 2 / 5 = 3 / 5
(b) Total number of parts each circle has = 5
We may observe that the first, second and third circles represent 5, 3 and 2 shaded parts out of 5 equal parts respectively. Clearly, fraction represented by the third circle is the difference between the fractions represented by the first and second circles.
Hence, 5 / 5 – 3 / 5 = 2 / 5
(c) Here we may observe that first, second and third rectangles represents 2, 3 and 5 shaded parts out of 6 equal parts, respectively. Clearly, fraction represented by the third rectangle is the sum of fractions represented by the first and second rectangles.
Hence, 2 / 6 + 3 / 6 = 5 / 6

= (9 + 14) / 30
(c) 4 / 9 + 2/ 7
Taking LCM 63
= [(4 × 7) + (2 × 9)] / 63
= (28 + 18) / 63
Taking LCM 21
= [(5 × 3) + (1 × 7)] / 21
= (15 + 7) / 21
= [(2 × 6) + (1 × 5)] / 30
= (12 + 5) / 30
Taking LCM 15
= [(4 × 3) + (2 × 5)] / 15
= (12 + 10) / 15
Taking LCM 12

= 4/ 3 + 11 / 3
= (4 + 11) / 3
= [(3 × 4) + 2] / 3 + [(3 × 4) + 1] / 4
= 14 / 3 + 13 / 4
= [(14 × 4) + (13 × 3)] / 12
= (56 + 39) / 12
= (16 – 7) / 5
(n) 4 /3 – 1 / 2
= [(4 × 2) – (1 × 3)] / 6
= (8 – 3) /6
2. Sarita bought 2 / 5 metre of ribbon and Lalita 3 /4 metre of ribbon. What is the total length of the ribbon they bought?
Ribbon length bought by Sarita = 2 / 5 metre
Ribbon length bought by Lalita = 3 / 4 metre
Total length of the ribbon bought by both of them = 2 / 5 + 3 / 4
Taking LCM 20
= [(2 × 4) + (3 × 5)] / 20
= (8 + 15) / 20
= 23 / 20 metre
∴ Total length of the ribbon bought by both Sarita and Lalita is 23 / 20 metre
Total amount of cake given to both of them = 3 / 2 + 4 / 3
= [(3 × 3) + (4 × 2)] / 6

▯ = [(1 × 2 + 5)] / 8
▯ = 1 / 2 + 1 / 5
▯ = [(1 × 5) + (1 × 2)] / 10
▯ = (5 + 2) / 10
▯ = 1 / 2 – 1 / 6
▯ = [(1 × 3) – (1 × 1)] / 6
▯ = (3 – 1) / 6
5. Complete the addition and subtraction box.
(a) 2 / 3 + 4 / 3
= (2 + 4) / 3
1 / 3 + 2 / 3
= (1 + 2) / 3
2 / 3 – 1 / 3
= (2 – 1) / 3
4 / 3 – 2 / 3
= (4 – 2) / 3
Hence, the complete given box is
(b) 1 / 2 + 1 / 3
= [(1 × 3) + (1 × 2)] / 6
= (3 + 2) / 6
1 / 3 + 1 / 4
= [(1 × 4) + (1 × 3)] / 12
= (4 + 3) / 12
1 / 2 – 1 / 3
= [(1 × 3) – (1 × 2)] / 6
= (3 – 2) / 6
1 / 3 – 1 / 4
= [(1 × 4) – (1 ×3)] / 12
= (4 – 3) / 12
1 / 6 + 1 / 12
= [(1 × 2) + 1] / 12
= (2 + 1) / 12
6. A piece of wire 7 / 8 metre long broke into two pieces. One piece was 1 / 4 metre long. How long is the other piece?
Total length of wire = 7 / 8 metre
Length of one piece of wire = 1 / 4 metre
Length of other piece of wire = Length of the original wire and this one piece of wire
= 7 / 8 – 1 / 4
= [(7 × 1) – (1 × 2)] / 8
= (7 – 2) / 8
∴ Length of the other piece of wire = 5 / 8 metre
7. Nandini’s house is 9 / 10 km from her school. She walked some distance and then took a bus for 1 / 2 km to reach the school. How far did she walk?
Distance of the school from house = 9 / 10 km
Distance she travelled by bus = 1 / 2 km
Distance walked by Nandini = Total distance of the school – Distance she travelled by bus
= 9 / 10 – 1 / 2
= [(9 × 1) – (1 × 5)] / 10
= (9 – 5) / 10
∴ Distance walked by Nandini is 2 / 5 km
8. Asha and Samuel have bookshelves of the same size partly filled with books. Asha’s shelf is 5 / 6 th full and Samuel’s shelf is 2/ 5 th full. Whose bookshelf is more full? By what fraction?
Fraction of Asha’s bookshelf = 5 / 6
Fraction of Samuel’s bookshelf = 2 / 5
5 / 6 = 5 / 6 × 5 / 5
= (5 × 5) / (6 × 5)
2 / 5 = 2 / 5 × 6 / 6
= (2 × 6) / (5 × 6)
25 / 30 > 12 / 30
5 / 6 > 2 / 5
∴ Asha’s bookshelf is more full than Samuel’s bookshelf
Difference = 5 / 6 – 2 / 5
= 25 / 30 – 12 / 30
Time taken by Rahul to walk across the school ground = 7 / 4 minutes
11 / 5 = 11 / 5 × 4 / 4
= (11 × 4) / (5 × 4)
7 / 4 = 7 / 4 × 5 / 5
= (7 × 5) / (4 × 5)
Clearly, 44 / 20 > 35 / 20
11 / 5 > 7 / 4
∴ Rahul takes less time than Jaidev to walk across the school ground
Difference = 11 / 5 – 7 / 4
= 44 / 20 – 35 / 20
Hence, Rahul walks across the school ground by 9 / 20 minutes

Q1: what is symmetry.
A1: Symmetry refers to a balanced and proportionate similarity between two halves of an object. An object is said to be symmetric if it can be divided into two or more identical parts that are mirror images of each other.
A2: There are three main types of symmetry: Line symmetry : When an object can be divided into two identical halves by a line. Rotational symmetry : When an object looks the same after a certain amount of rotation. Point symmetry : When every part of an object has a matching part at an equal distance from a central point.
A3: Line symmetry occurs when an object can be divided into two identical halves by a straight line. The line is called the line of symmetry or axis of symmetry. For example, a square has four lines of symmetry.
A4: A circle has an infinite number of lines of symmetry because it can be divided into identical halves by any line passing through its center.
A5: Rotational symmetry occurs when an object looks the same after being rotated by a certain angle around a central point. For example, a regular pentagon has rotational symmetry because it looks the same after a rotation of 72 0 .
A6: The angle of rotation is the smallest angle by which an object can be rotated to look exactly the same as its original position. For example, the angle of rotation of an equilateral triangle is 12 0 .
A7: Yes, an object can have both line and rotational symmetry. For example, a square has four lines of symmetry and also has rotational symmetry of order 4.
A10: We provide case study questions for CBSE Class 7 Maths on our website . Students can visit the website and practice sufficient case study questions and prepare for their exams. If you need more case study questions, then you can visit Physics Gurukul website. they are having a large collection of case study questions for all classes.
A11: To find the line of symmetry of a shape, try dividing the shape into two identical halves. If the halves are mirror images of each other, the line along which the division is made is the line of symmetry.
