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.
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?

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.
