Answer: 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
