Student's incorrect answer on a math problem about fractions is corrected by a teacher, highlighting a common misconception about comparing fractions.
A math worksheet question about pizza fractions with a student's handwritten answer crossed out and corrected by a teacher. The student wrote "Marty's pizza is bigger than Luis's pizza," but the teacher wrote "That is not possible because 5/6 is greater than 4/6 so Luis ate more." The question asks how Marty could have eaten more pizza than Luis if Marty ate 4/6 and Luis ate 5/6 of their respective pizzas.
