Maths Class 6 Chapter 7 Exercise 7.3 Question Answer

Solutions For All Chapters Maths Class 6

Ex 7.3 Class 6 Maths Question 1.
Write the fractions. Are all these fractions equivalent?

Solution:

Since all the fractions in their simplest form are not equal.
∴ They are not equivalent fractions.

Ex 7.3 Class 6 Maths Question 2.
Write the fractions and pair up the equivalent fractions from each row.

Solution:

The following pairs fractions:represent the equivalent fractions.
(a) and (ii) = 1/2
(b) and (iv) = 2/3
(c) and (i) = 1/3
(d) and (v) = 1/4
(e) and (iii) = 3/4

Ex 7.3 Class 6 Maths Question 3.
Replace in each of the following by the correct number:

Solution:

Ex 7.3 Class 6 Maths Question 4.
Find the equivalent fraction of 3/5 having

(a) denominator 20

(b) numerator 9

(c) denominator 30

(d) numerator 27

Solution:

(a) Here, we require denominator 20.
Let N be the numerator of the fractions.

∴ The required fraction is 12/20
(b) Here, we required numerator 9.
Let D be the denominator of the fraction.

∴ The required fraction is 9/15.

∴ The required fraction is 18/30.

(d) Here, we required numerator 27.
Let D be the denominator of the fraction.

∴ The required fraction is 27/45.

Ex 7.3 Class 6 Maths Question 5.
Find the equivalent fraction of 36/48 with

(a) numerator 9

(b) denominator 4

Solution:

(a) Given that numerator = 9

So, the equivalent fraction is 9/12.

(b) Given that denominator = 4
∴ N/4 = 36/48 ⇒ N x 48 = 4 x 36
⇒ N = 4×36/48 = 3
So, the equivalent fraction is 3/4 .

Ex 7.3 Class 6 Maths Question 6.
Check whether the given fractions are equivalent:

Solution:
(a) 5/9 and 30/54
We have 5 x 54 = 270
and 9 x 30 = 270
Here 5 x 54 = 9 x 30
∴ 5/9 and 30/54 are equivalent fractions.

(b) 3/10 and 12/50
We have 3 x 50 = 150
and 10 x 12 = 120
Here 3 x 50 ≠ 10 x 12
∴ 3/10 and 12/50 are not equivalent fractions.

Ex 7.3 Class 6 Maths Question 7.
Reduce the following fractions to simplest form:

Solution:

Ex 7.3 Class 6 Maths Question 8.
Ramesh had 20 pencils, Sheelu had 50 pencils and Jamaal had 80 pencils. After 4 months, Ramesh used up 10 pencils, Sheelu used up 25 pencils and Jamaal used up 40 pencils. What fraction did each use up? Check if each has used up an equal fraction of her/his pencils.

Solution:

Ramesh used up 10 pencils out of 20 pencils.
