7/24= 3/24 +4/24
= 1/8 +1/6

8/15 = 5/15 +3/15
= 1/3 +1/5

I'll leave you to see if you can do the other.

They would only use 1 as a numerator and then add up several fractions to get the desired result. so

15/16 = 1/2 + 1/4 + 1/8 + 1/16

8/15 = 1/3 + 1/5

7/24 = 1/6 + 1/8

It's explained better here..

oppps, sorry factor, I spoiled that one somewhat!

You'll find 15/16 is a bit harder.
You may need an extra step
Start by looking for a half, then a quarter, then break down what's left into Egyptian fractions too.
