To find out how much pizza was left after John ate, we need to calculate the total amount of pizza that John ate and subtract it from the total amount of pizza they bought.
First, let's calculate how much pizza John ate:
John ate 2/4 of a pizza. Since 2/4 is equivalent to 1/2, we can say John ate 1/2 of a pizza.
Now, let's calculate the total amount of pizza that John, Sara, Tom, and Joy bought:
Since they bought 2 pizzas of the same size and divided it among themselves, each person received 1/4 of a pizza.
There are 4 people in total, so the total amount of pizza they bought is:
4 * 1/4 = 4/4 = 1 pizza.
Lastly, let's calculate how much pizza was left:
The total amount of pizza they bought was 1 pizza, and John ate 1/2 of a pizza.
So, the amount of pizza left is 1 - 1/2 = 1/2 of a pizza.
Therefore, after John ate, there was 1/2 of a pizza left.
