Over Thanksgiving break Peyton made a Pizza, she cut the pizza into 12 slices. Peyton's mom ate 4 slices, Peyton's dad ate 5 slices, and Peyton ate the rest of the pizza. What fraction of the pizza did Peyton eat? Simplify the answer. *

3/12 = ____

To find the fraction of the pizza that Peyton ate, we first need to determine how many slices were eaten in total.

Peyton's mom ate 4 slices and Peyton's dad ate 5 slices, so in total they ate 4 + 5 = 9 slices.

Since the pizza was initially cut into 12 slices, Peyton ate 12 - 9 = 3 slices.

To find the fraction, we divide the number of slices Peyton ate (3) by the total number of slices (12).

Therefore, Peyton ate 3/12 slices of the pizza.

To simplify the fraction, we can divide the numerator and the denominator by the greatest common divisor (GCD) of 3 and 12, which is 3.

3/12 simplifies to 1/4.

Therefore, Peyton ate 1/4 of the pizza.

To find the fraction of the pizza that Peyton ate, we need to first calculate how many slices are left after Peyton's mom and dad have eaten.

Peyton's mom ate 4 slices and Peyton's dad ate 5 slices, which makes a total of 4 + 5 = 9 slices eaten by both of them.

Since Peyton originally cut the pizza into 12 slices, the number of slices left for Peyton to eat is 12 - 9 = 3 slices.

Therefore, Peyton ate 3 slices out of the 12 slices.

To simplify the fraction, we can see that both 3 and 12 can be divided by 3:
3 / 3 = 1
12 / 3 = 4

So, Peyton ate 1/4 of the pizza.
