Answer 5

OK there are 5 parts of the bill total -- 5 fifths. Heather paid 3. So how many are left over for Jen to pay?

Answer 7

yes... so what part of the bill is that expressed as a fraction?

Answer 8

2/5

Answer 9

Answer 20

okay so similarly let's call the total amount of the bill "X". we know that 2/5 of the bill is $8 so that means
