Johny answered
`(17)/(20)` questions correctly. To change this into percent, just multiply both the numerator and denominator by the number that makes the denominator equal 100. In this case, 5 would make 20 equal 100, so we multiply both the top and bottom by 5.

`(17)/(20) *(5)/(5)=(85)/(100)`

Your numerator will be your percentage if the denominator is 100.
