Answer:
3/8
Explanation:
if cameron ate 1/4 of a full pie, there would be 3/4 of it left. amy ate half of what is left so to figure this out, we should make the 3 into an even number, and the lowest fraction of this would be 6/8, and half of this is 3/8, so after amy had her share, there was 3/8 of the pie left.
