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?

1 answer

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}}.
