If I have three pizzas all the same size and one pizza is cut into halves, one is cut into fourths, and one is cut into sixths. All together I have twelve pieces of pizza. If I eat four did I eat 4/12 of the pizza?

No. The pieces aren't the same size.

To find out if you ate 4/12 of the pizza, we need to determine the total number of pieces in the three pizzas.

First, let's calculate the number of pieces in each pizza:

- The first pizza is cut into halves, so it has 2 pieces.
- The second pizza is cut into fourths, so it has 4 pieces.
- The third pizza is cut into sixths, so it has 6 pieces.

To find the total number of pieces, we add up the pieces from each pizza:

2 + 4 + 6 = 12

Since you ate 4 pieces of pizza and there are 12 pieces in total, you indeed ate 4/12 of the pizza.
