Question

johnny at 1/2 of a pizza, sue has 1/2 of another pizza, johnny said he ate more than sue, but sue says they both at the same amount, is johnny right?

Answer 1

If Johnny's pizza is larger than Sue's, he ate more pizza, in square inches consumed.

On the other hand, they each ate 1/2 pizza.

Either can be said to be correct, depending on your interpretation, and the facts of the problem.

Assuming both pizzas were the same, Johnny is wrong.

Answer 2

it doesn't state that sue ate 1/2 of the other pizza. so if johnny ate 1/2 of a pizza and sue has 1/2 of another pizza. johnny is right. he ate his half....sue still has 1/2.
