Question

find three rational
number between 4/10 and 5/10​

Answer 1

Answer:

First we have to find rational number between 4/10 and 5/10

To find we have to take the average (4/10 + 5/10) * 1/2 = 4.5/10 or 9/20

Rational number between 4/10 and 9/20 = (8/20 + 9/20) * 1/2 = 17/40

Rational number between  5/10 and 9/20 = (10/20 + 9/20)* 1/2 =19/40

So, the 3 rational numbers are  9/20 , 17/40 and 19/40
