To find out how many times more pizza Joe has eaten than Jane, we first need to calculate the respective amounts of pizza each of them has eaten.
Joe has eaten 3/5 of a pizza, while Jane has eaten one quarter of a pizza.
To compare these fractions, we need to find a common denominator. In this case, the least common multiple of 5 and 4 is 20.
Let's convert the fractions to have a denominator of 20:
Joe: (3/5) * (4/4) = 12/20
Jane: (1/4) * (5/5) = 5/20
Now we can compare their fractions:
Joe has eaten 12/20 of a pizza, while Jane has eaten 5/20 of a pizza.
To find out how many times more pizza Joe has eaten than Jane, we divide Joe's amount by Jane's amount:
(12/20) / (5/20) = (12/20) * (20/5) = 12/5 = 2.4
Therefore, Joe has eaten 2.4 times more pizza than Jane.
