Luis is correct. Because Tito ate 2 eighths of one pizza, 3 eighths of another and 4 eighths of another, resulting in Tito eating 9 eighths of pizza ( 1 whole pizza and 1 eighth). Luis then ate 5 eighths of one pizza and 4 eights of another pizza, also resulting in 9 eighths. This question is based around common denominators.
