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
