Questions and Solutions for NCERT Class 6th Mathematics Chapter 7 – Fractions – Exercise 7.5

1. Write these fractions appropriately as additions or subtractions :

Solution:

(a) 1/5 + 2/5 = (1+2) / 5 = 3/5

(b) 5/5 – 3/5 = (5 – 3) / 5 = 2/5

(c) 2/6 + 3/6 = (2+3) / 6 = 5/6

2. Solve :

(a) 1/18 + 1/18

Solution:

1/18 + 1/18 = 2/18 = 1/9

(b) 8/15 + 3/15

Solution:

8/15 + 3/15 = (8+3) / 15 = 11/15

(c) 7/7 – 5/7

Solution:

7/7 – 5/7 = ( 7-5) / 7 = 2/7

(d) 1/22 + 21/22

Solution:

1/22 + 21/22 = (1+21)/22 = 22/22 = 1

(e) 12/15 – 7/15

Solution:

12/15 – 7/15 = (12-7)/15 = 5/15 = 1/3

(f) 5/8 + 3/8

Solution:

5/8 + 3/8 = (5+3)/8 = 8/8 = 1

(g) 1 – 2/3

Solution:

1 – 2/3 = 3/3 – 2/3 = (3-2) / 3 = 1/3

(h) 1/4 + 0/4

Solution:

1/4 + 0/4 = (1+0)/4 = 1/4

(i) 3 – 12/5

Solution: 

3 – 12/5 = 15/5 – 12/5 = (15-12) / 5 = 3/5

3. Shubham painted 2/3 of the wall space in his room. His sister Madhavi helped and painted 1/3 of the wall space. How much did they paint together?

Solution: Fraction of wall painted by Shubham = 2/3

fraction of wall painted by Madhavi = 1/3

Total wall space painted = 2/3 + 1/3 = 3/3

Thus, they painted complete wall.

4. Fill in the missing fractions.

(a) 7/10 – ___ =  3/10 

(b)___ − 3/21 = 5/21

(c) __ – 3/6 =  3/6

(d) __ + 5/27 = 12/27

Solution:

(a) 7/10 – 4/10 =  3/10 

(b) 8/21 − 3/21 = 5/21

(c) 6/6 – 3/6 =  3/6

(d) 7/27 + 5/27 = 12/27

5. Javed was given 5/7 of a basket of oranges. What fraction of oranges was left in the basket?

Solution: Total fraction of oranges in the basket = 1 =7/7

fraction of oranges given to Javed = 5/7

Fraction of oranges left = 7/7 – 5/7 = 2/7

Thus, 2/7 oranges were left in the basket.
