**NCERT Solutions for Class 7 Maths Chapter 9 Rational Numbers Exercise 9.1**

Ex 9.1 Class 7 Maths Question 1.

List five rational numbers between:

(i) -1 and 0

(ii) -2 and -1

(iii) (frac{-4}{5} text { and } frac{-2}{3})

(iv) (frac{1}{2} text { and } frac{2}{3})

Solution:

(i) -1 and 0

Converting each of rational numbers as a denominator 5 + 1 = 6, we have

Hence, the required five rational numbers between -1 and 0 are (frac{-5}{6}, frac{-2}{3}, frac{-1}{2}, frac{-1}{3} text { and }-frac{1}{6})

(ii) -2 and -1

Converting each of rational numbers as a denominator 5 + 1 = 6, we have

(iii) (frac{-4}{5} text { and } frac{-2}{3})

Converting each of the rational numbers as a denominator 5 × 3 = 15, we have

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

(iv) (frac{1}{2} text { and } frac{2}{3})

Converting each of the rational numbers in their equivalent rational numbers, we have
