marty ate 4/6 of his pizza and luis ate 5/6 of his pizza. marty ate more pizza than luis. how is that possible?
Marty's pizza was bigger. If he had a large pizza, and it had 12 slices then he would have had 8 slices. if Luis had a personal pizza, and it had 6 slices, then he would have only had 5 slices. So, Marty ate more pizza.
