if you have the known value and know that it is 20% all you have to do is take 100 and divide it by 20 which equals 4. Then multiply your known value by the number 4 that you found by taking 100% and dividing it by the percentage of the known value.

Unfortunately, 100/20 is 5, not 4!
So you need to multiply by 5.
