John ate 1/2

of a pizza for lunch, and he ate 1/3
of what was left for dinner. How much pizza did John eat for dinner?

To find out how much pizza John ate for dinner, we need to find out how much was left after lunch.

If John ate 1/2 of the pizza for lunch, this means 1 - 1/2 = <<1-1/2=1/2>>1/2 of the pizza was left.

John then ate 1/3 of what was left for dinner.

1/3 of 1/2 can be found by multiplying the fractions: 1/3 * 1/2 = <<1/3*1/2=1/6>>1/6

John ate 1/6 of a pizza for dinner. Answer: \boxed{\frac{1}{6}}.

To find out how much pizza John ate for dinner, we need to follow these steps:

Step 1: Determine how much pizza was left after lunch.
Since John ate 1/2 of the pizza for lunch, there would be 1 - 1/2 = 1/2 of the pizza left after lunch.

Step 2: Calculate the amount of pizza John ate for dinner.
Since John ate 1/3 of what was left for dinner, we need to find 1/3 of 1/2.
To do this, we multiply 1/3 by 1/2: (1/3) * (1/2) = 1/6.

Therefore, John ate 1/6 of the pizza for dinner.

To find out how much pizza John ate for dinner, we first need to understand the context of the problem.

John ate 1/2 of a pizza for lunch. This means that if the whole pizza is represented by 1, John ate 1/2 or half of it.
After eating lunch, there would be 1/2 of the pizza left.

Then, John ate 1/3 of what was left for dinner. So, we need to determine 1/3 of the remaining 1/2 of the pizza.

To calculate this, we multiply 1/3 by 1/2:

1/3 * 1/2 = 1/6

Therefore, John ate 1/6 of the pizza for dinner.

In conclusion, John ate 1/6 of the pizza for dinner.
