Julio ordered towo pizzas for dinner Friday. Dad ate 3/4 of one pizza, Jenny ate 1/8 of a pizza, Danny ate 1/4 of a pizza, and Mom ate 1/2 of a pizza. What fraction of a pizza was left for a midnight snack?
Mr. L answered to my question like this:
6/8 + 1/8 + 2/8 + Mom = ?/8
but I would like to know if the answer will be 13/8 = 1 5/8.
Is that right?
Thank you for helping me with this problem.
They've eaten 1 5/8 of the two pizzas.
1 8/8 - 1 5/8 = 3/8 left for the snack.
To find the fraction of pizza left for a midnight snack, let's calculate the total amount of pizza consumed first.
Dad ate 3/4 of a pizza.
Jenny ate 1/8 of a pizza.
Danny ate 1/4 of a pizza.
Mom ate 1/2 of a pizza.
To find the total amount eaten, we need to find a common denominator for these fractions. The common denominator for 4, 8, and 2 is 8. So let's express each fraction with a denominator of 8.
Dad ate (3/4) * (2/2) = 6/8 of a pizza.
Jenny ate (1/8) * (1/1) = 1/8 of a pizza.
Danny ate (1/4) * (2/2) = 2/8 of a pizza.
Mom ate (1/2) * (4/4) = 4/8 of a pizza.
Now, let's add up the fractions:
6/8 + 1/8 + 2/8 + 4/8 = 13/8
So, the total amount of pizza consumed is 13/8.
Since there were 2 pizzas in total, we can say that a whole pizza is 8/8 of a pizza. Therefore, the fraction of a pizza left for a midnight snack is:
2 - (13/8) = 16/8 - 13/8 = 3/8
So, the answer is 3/8 of a pizza left for a midnight snack.
In the answer, you mentioned 13/8 as 1 5/8. However, 13/8 is equivalent to 1 5/8, so your answer is correct. It can be expressed as both a mixed number (1 5/8) and an improper fraction (13/8).
