Question

Joe has eaten 3/5 of a pizza. Jane has eaten 1/7 of a pizza. How many times more pizza has Joe eaten than Jane in an improper fraction?

Answer 1

lowest common denominator = 35


`(3)/(5)` =
`(21)/(35)`


`(1)/(7) = (5)/(35)`


`(21)/(35) - (5)/(25) = (16)/(35)`

Answer 2

Joe has eaten (21/5) times more than Jane.
Divide (3/5) with (1/7)...you'll get 21/5
If you want to check this, multiply 21/5 by 1/7....you'll get 3/5 which is what Joe has eaten!

Now convert 21/5 into improper by doing long divison..it'll be 4(1/5)
