**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
