Question

Which of the following rational number lies between -3/4 and -1/13

Answer 1

One rational number lying between a and b is (a + b)/2.

1. One rational number lying between 1.4 and 1.3 = (1.4 + 1.3)/2 = 2.7/2 = 27/20 = 1.35.

Hence, 1.35 is a rational number lying between 1.4 and 1.3.

2. One rational number lying between 0.75 and 1.2 = (0.75 + 1.2) / 2 = 1.95/2 = 195/200 = 0.975

Hence 0.975 is the rational number lying between 1.2 and 0.75
