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?
It will be 13/8 = 1 5/8.
Is that right?
Make both pizzas cut into 8 slices. Then make all fractions into eighths so Dad ate 3/4 or 6/8, Jenny ate 1/8, Danny ate1/4 or 2/8 and so on.
6/8 + 1/8 + 2/8 + Mom = ?/8

No
To find the fraction of pizza that was left for a midnight snack, we need to calculate the total amount of pizza eaten and subtract it from the original total.
First, let's add up the fractions of pizza eaten:
Dad: 3/4 of one pizza
Jenny: 1/8 of a pizza
Danny: 1/4 of a pizza
Mom: 1/2 of a pizza
To add these fractions, we need to find a common denominator. In this case, the smallest common denominator is 8. So, let's convert all the fractions to have a denominator of 8:
Dad: 3/4 * 2/2 = 6/8
Jenny: 1/8
Danny: 1/4 * 2/2 = 2/8
Mom: 1/2 * 4/4 = 4/8
Now that we have a common denominator, we can add the fractions together:
6/8 + 1/8 + 2/8 + 4/8 = 13/8
Next, we want to determine how much pizza was left. To do this, we'll subtract the sum of the fractions eaten from 1 (since 1 represents the whole pizza):
1 - 13/8 = 8/8 - 13/8 = -5/8
The result is -5/8, which indicates that there is a deficit of 5/8 of a pizza. This means that the amount eaten exceeded the whole pizza, and there is no pizza left for a midnight snack.
