Question

Find four rational number between -2 and 2​

Answer 1

ANSWER

If a and b are two rational no.s, then (a + b/2) will be the rational no. between a and b.

So,

rational no. between 2 and -2 will be

{2 + (-2)}/2 = 0

Rational no. between 0 and 2

(0 + 2)/2 = 1

Rational no. between 1 and 2

(1 + 2)/2 = 3/2

Rational no. between 3/2 and 2

(3/2 + 2)/2 = (3 + 4)/2 = 7/2

So, four rational no.s between

2 and -2 will be

0, 1, 3/2, 7/2

In this way, we can find infinite no. of rational no.s between two rational no.s
