Question

two apple pies are sliced into 1/10s. 2/10s of one apple pie are eaten with custard and 7/10s of the other apple pie are eaten with cream. how many pieces of apple pie were left?

Answer 1

Answer:

11 pieces were left.

Step-by-step explanation:

Each apple pie was sliced into ten. There were 2 apple pies, so 10*2=20.

2/10 of one pie were eaten, and 7/10 of the other. so 9/10 were eaten in total. But since there were 20 pieces, it would be 9/20 meaning there are 11 pieces left.
