Marty ate 1/4 of a pizza. Rob ate 1/5 of a pizza . How could rob eaten more pizza than Marty?

Did Rob have a larger pizza?

Yes, Rob had a larger pizza

To determine how Rob could have eaten more pizza than Marty, we need to compare the fractions of pizza each of them ate. Marty ate 1/4 of a pizza, while Rob ate 1/5 of a pizza.

To make the fractions easier to compare, we can find a common denominator for both fractions. The common denominator for 4 (the denominator of Marty's fraction) and 5 (the denominator of Rob's fraction) is 20.

To find out how much each person ate in terms of 20 equal parts (the common denominator), we need to multiply the numerator (the number on top) of each fraction by the same value we multiplied the denominator with.

For Marty:
1/4 * 5/5 = 5/20

For Rob:
1/5 * 4/4 = 4/20

By converting both fractions to 20 parts, we see that Marty ate 5 out of 20 parts of a pizza, while Rob ate 4 out of 20 parts.

Since 5 is greater than 4, Marty ate more pizza than Rob, breaking the original assumption that Rob ate more. Therefore, based on the given information, Rob could not have eaten more pizza than Marty.
