Even if it is purely a math question though, it never specifies “Their pizzas are the same size.” The student literally answered how this is possible in a reasonable way that satisfies the mathematical requirements, when the teacher is expecting an impossible answer of “it’s not” after saying in this scenario that Marty did in fact eat more.

Yeah, if the question was “Is this possible?” then the teacher’s answer would be reasonable.
But the “how” in the question implicates that it’s actually factual and the student should come of with an explanation how. Which they did perfectly.
Both of your questions would be satisfied by the student’s answer though
True, even with the “Is this possible?” the student’s answer should have been ok. But with the “how” the teacher’s answer is plainly wrong.
