Question

There are two identical glasses. One glass is 3/5 full. The other is 7/8 full.

What fraction of the other glass is filled?

Answer 1

A: 19/40

Explanation:

LCD = 40

7*5=35 ->35/40

3*8=24 ->24/40

combine like terms

for simplicity, I'll use a mixed number

1 19/40

subtract your "full glass"

1 19/40 - 1 = 19/40
