NCERT 7th Maths Chapter 9, class 7 Maths Chapter 9 solutions

Exercise 9.1

1. List five rational numbers between:

(i) -1 and 0

(ii) -2 and – 1

(iii) -4/5 and -2/3

(iv) -1/2 and 2/3

Answer

(i) -1 and 0

Let us write -1 and 0 as rational numbers with denominator 6.

Therefore, five rational numbers between -1 and 0 would be

(ii) -2 and -1

Let us write -2 and -1 as rational numbers with denominator 6.

Therefore, Five rational numbers between -2 and -1 would be

(iii) -4/5 and -2/3

Let us write -4/5 and -2/3 as rational numbers with the same denominators.

Therefore, five rational numbers between -4/5 and -2/3 would be

(iv) -1/2 and 2/3

Let us write -1/2 and 2/3 as rational numbers with the same denominators.

Therefore, five rational numbers between -1/2 and 2/3 would be

2. Write four more rational numbers in each of the following patterns:

Answer

Therefore, four equivalent rational numbers are

(ii) 

Therefore, the next four rational numbers of this pattern would be

(iii) 

Therefore, the next four rational numbers of this pattern would be

(iv) 

Therefore, the next four rational numbers of tins pattern would be

3. Give four rational numbers equivalent to:

(i) -2/7

(ii) 5/-3

(iii) 4/9

(iv) -2/7

Answer

(i)

Therefore, four equivalent rational numbers are

(ii) 5/-3

Therefore, four equivalent rational numbers are

(iii) 4/9

Therefore, four equivalent rational numbers are

4. Draw the number line and represent the following rational numbers on it: 

(i) 3/4

(ii) -5/8

(iii) -7/4

(iv) 7/8

Answer

(i) 3/4

(ii) -5/8

(iii)  -7/4

(iv) 7/8
