Find a rational number between 1/8 and 2/4

A rational number is any number which can be expressed as a fraction of two integers. The set of all rational numbers is ℚ.

The answer would be any rational number between 1/8 and 2/4, i.e. find x where
1/8<x<2/4 x∈ℚ.

Draw the two limits, 1/8 and 2/4 on the number line. Any rational number between the two numbers would be an answer.

As an example, the average of the two limits is a rational number between the two limits:
(1/8+2/4)=(1/8 + 4/8) = 5/8
