4 girls shared a pizza equally for lunch. If one of them gave away 1/3 of her share, what fraction of the pizza had she left?
1. 1/12
2. 1/6
3. 1/4
4. 2/3
(1/3)(1/4) = 1/12
Thanks Ms. Sue
The answer given is 1/6???
That's right. I goofed! Sorry.
She gave away 1/12 of the pizza. She has 1/6 left.
(2/3) * (1/4) = 2/12 = 1/6
Thank you Ms. Sue :)
To solve this problem, we need to start by finding the original fraction each girl received.
Since 4 girls shared the pizza equally, we need to divide the whole pizza into 4 equal parts. This means each girl received 1/4 (one-fourth) of the pizza.
Now, we need to find what fraction of her share one girl gave away. It is given that one girl gave away 1/3 (one-third) of her share.
To find out how much pizza she gave away, we multiply her share (1/4) by the fraction she gave away (1/3):
1/4 * 1/3 = 1/12
Therefore, she gave away 1/12 (one-twelfth) of the pizza.
To find the fraction of the pizza she had left, we need to subtract the fraction she gave away (1/12) from her original share (1/4):
1/4 - 1/12 = 3/12 - 1/12 = 2/12
Simplifying the fraction 2/12, we get:
2/12 = 1/6
Therefore, the fraction of the pizza that she had left is 1/6.
So, the correct answer is option 2. 1/6
