The rational number halfway between 2/4 and 1/8

5/16, or 0.3125

First, add the two fractions.  Both fractions must have the same denominator.

2/4 → 4/8

1/8

4/8 + 1/8 = 5/8

Now, divide by 2:

5/8/2 = 5/16

I also found another way to solve this, if you're interested:

First, convert both fractions to their sixteenths form:

2/4: 8/16

1/8: 2/16

Then, identify the number midway between the numerators, being 5.

So, the answer is 5/16
