Apologies for the error. Let's calculate the correct answer:
1 3/5 x 2/15 = (8/5) x (2/15)
= (8 x 2) / (5 x 15)
= 16 / 75
Therefore, the correct answer is:
D. 16/75

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?
A. 1/15
B. 8/15
C. 10/15
D. 4/15
Let's work through this step by step:
1. Susan gave Joe 1/3 of the pizza, which means she had 1 - 1/3 = 2/3 of the pizza left.
2. Susan gave her mother 1/5 of what was left, which is 2/3 * 1/5 = 2/15 of the pizza.
3. Susan ate the rest, which is 2/3 - 2/15 = 10/15 of the pizza.
Therefore, Susan ate 10/15 of the pizza.
The correct answer is: C. 10/15
you sure its C
Let's recheck the calculations:
Given:
Pizza = 1 whole
1. Susan gave Joe 1/3 of the pizza.
Amount left = 1 - 1/3 = 2/3
2. Susan gave her mother 1/5 of what was left.
Amount given to her mother = (2/3) * (1/5) = 2/15
3. Susan ate the rest herself.
Amount Susan ate = 2/3 - 2/15 = (10/15) - (2/15) = 8/15
Therefore, Susan ate 8/15 of the pizza.
The correct answer is B. 8/15.
