devon & Trisha ate 1/4 +3/8
=5/8 of the pizza
...
Michael ate 1-5/8

You can put this solution on YOUR website! We are looking for 
where d is slices eaten by Devon, t is slices eaten by Trisha, m is slices eaten by Michael, and p is total Pizza slices.
We are given that they ate the entire 8 slices, so
Devon ate 1/4 of the pizza, or (1/4)*8 or 2 slices.
Trish ate 3/8 of the pizza or (3/8)*8 or 3 slices.
Since all 8 slices were eaten, Michael must have eaten the remaining 3 slices!
Thus, or  which checks out!
EDIT: Of course I forgot to put it into the proper form!
Since Michael ate 3 pieces, he ate 3 of the 8 pieces, which means he ate 3/8 of the pizza!
Michael ate 3 slices of pizza, or 3/8 of the entire pizza!
I hope this helps!

---------------------------------
Michael ate 8/8-(1/4)-(3/8) = (8/8)-(2/8)-(3/8) = 3/8 of the pizza
