Answer:the fraction of the cherry pie that they ate altogether is 11/15
Explanation:
Let x represent the total size of the cherry pie that Andy and April shared.
Andy ate 2/5 of the pie. This means that the total amount of cherry pie that Andy ate is 2/5 × x = 2x/5
April ate 1/3 of the pie. This means that the total amount of cherry pie that April ate is 1/3 × x = x/3
The amount of the cherry pie eaten by both Andy and April would be
2x/5 + x/3 = 11x/15
Therefore, the fraction of the cherry pie that they ate altogether would be
(11x/15)/x = 11/15
