Chapter 9 Rational Numbers Exercise 9.1
Question 1.
List five rational numbers between:
(i) -1 and 0
(ii) -2 and -1

Solution:
(i) -1 and 0
Converting each of rational numbers as a denominator 5 + 1 = 6, we have (ii) -2 and -1
Converting each of rational numbers as a denominator 5 + 1 = 6, we have Since there is only one integer i.e. -11 between -12 and -10, we have to find equivalent rational numbers. Question 2.
