To compare the sizes of fractions, we need to find a common denominator. In this case, the least common multiple of 5 and 20 is 20. Converting four fifths to have a denominator of 20, we get 16/20. Comparing 16/20 to 17/20, we see that 17/20 is bigger than 16/20. Therefore, seventeen twentieths is bigger than four fifths.
