You would set up a ratio. First you would start with your part over whole, equal to your percent over 100.
It would look something like
25 = x
---- ----
100 100
Then you would cross multiply, meaning you would multiply the opposites
it would look like 25 times 100 (the 100 under the "x")
and "x" times 100 (the 100 under the 25)
100x = 2500
divide by 100
x = 25%
