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?

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. 
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.
