Question

What number is midway between 2/5 and 1?
4/5
5/6
7/10

Answer 1

Answer: JcAlmighty's answer was correct. It was 7/10

Answer 2

The answer is 7/10.

A number which is a midway between two numbers is actually average of those two numbers.
Let x be our desirable midway number:
x = (2/5 + 1)/2 =(2/5 + 5/5)/2= (7/5)/2 = 7/5 * 1/2 = 7/10
