A simple tool to remember is: IS over OF equals percent over 100.
If we put this into a proportion, we get:
IS/OF = percent/100.
Just put all percent problems into this format, and solve the proportion.
Example: 12.5 IS what percent OF 75?
Or,
12.5 IS | what percent | OF 75?
Just put these numbers into the proportion: (We will use x for the percent, as that is the unknown we are solving for)
12.5/75 = x/100.
Then solve by cross multiplying:
75x = 1250.
Then divide by 75:
x = 1250/75,
x = 16 2/3 %
