It is entirely possible and his answer was correct. Question was phrased incorrectly, if the teacher wanted an answer “it is not possible” he should have said both pizzas were the same size.
Not only that, the two statements in the premise are simply given. How is the child to know one of them is false? At that point, why not say Marty ate more than Luis and therefore the fractions must be different? Maybe the fractions are wrong and Luis ate more.
Just an absolutely terrible question if that’s supposed to be the answer. I’d guess the teacher didn’t write the question and didn’t understand the answer.
A third option is that there is a third pizza eater who also ate 4/6th of their pizza and gave 2/6th up Marty in exchange for the 2/6th Marty didn’t eat.

Or yeah maybe it was a larger pizza.
