Question

Gary has 2 apple pies and each is divided into 8 equal parts. He serves 4/8 of the first pie. How much pie does he have left?

Answer 1

So 2 whole pies with each 8 slices. He gives half of one so 1 1/2

2/1 - 4/8 = 16/8 - 4/8 = 12/8 simplified to 1 1/2

But literally it's just half missing so 2 - 1/2 = 1 1/2 also works.

Answer 2

1/2 because he has 16 pieces gives 4/8 which is a half and therefore has a half left
