### Ex 9.1 Class 7 Maths Question 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

Solution:
(i) 1 and 0
Let us convert the given rational numbers as a denominator 5 + 1 = 6, we get

Hence, the five rational numbers between 1 and 0 are 5/6, −2/3, −1/2, −1/3 and 1/6.

(ii) 2 and 1

Let us convert the given rational numbers as a denominator 5 + 1 = 6, we get

(iii) 4/5 and 2/3
Let us convert the given rational numbers as a denominator 5 × 3 = 15, we get

Since there is only one integer, i.e., -11 between -12 and -10, we have to find equivalent rational numbers of -12/15 and -10/15.

(iv) 1/2 and 2/3
Let us convert the given rational numbers in their equivalent rational numbers, we get
