The answer is Ron. First, you have to get a common denominator for the three fractions and the common denominator is 8. So 3/4 is equal to 6/8. Next, you compare the three fractions. 7/8 is larger than 5/8 because the numerator 7 is bigger than 5. 7/8 is bigger than 6/8 so 7/8 is larger than all the fractions. Therefore, Ron ate the most.
