Hello!
I'd love to help.
An easy method to finding a percentage is converting it into a decimal.
First though, we must simplify 15/20, which would be 3/4, (please let me know if you need the process of simplification)
Then we find the decimal.
We divide the numerator by the denominator.
3 ÷ 4 = .75
Which means that our final answer is:
75%
