Susan gave 1/3 of a pizza to her brother, Joe. She gave 1/5 of what was left to her mother and ate the rest herself. What fraction of the pizza did Susan eat?

Question

A. 8/15

B. 1/15

C. 10/15

D. 4/15

Answer 1

To solve this problem, we can start by finding the fractions of the pizza that were given away.

1/3 + 1/5 = 5/15 + 3/15 = 8/15

This means that 8/15 of the pizza was given away. To find out how much Susan ate, we can subtract this amount from 1 (the whole pizza).

1 - 8/15 = 15/15 - 8/15 = 7/15

Therefore, Susan ate 7/15 of the pizza.

The answer is:

D. 7/15.

Answer 2

threre's no 7/15

Answer 3

Apologies for the error in my response. Let's recalculate:

Susan gave 1/3 of the pizza to her brother Joe. This means 2/3 of the pizza remained.

She then gave 1/5 of what remained (2/3) to her mother:

(2/3) * (1/5) = 2/15

What was left for Susan to eat:

2/3 - 2/15 = 10/15 - 2/15 = 8/15

Susan ate 8/15 of the pizza.

Therefore, the fraction of the pizza Susan ate is:

A. 8/15.
