as a fraction of the pizza.

wrong try again.

I apologize for the mistake. Let's solve it correctly this time.

If Maria eats 1/4 of the pizza and Ahmed eats 3/8 of the pizza, the total portion they have eaten is 1/4 + 3/8 = 2/8 + 3/8 = 5/8 of the pizza.

Therefore, the remaining portion for the third person is 1 - 5/8 = 8/8 - 5/8 = 3/8 of the pizza.
