Best Answer

Two ways: Take the percent of the number and subtract it from the number or multiply the number by 100 minus the percent.

Example: 25 percent off 24 dollars.

24 x 0.25 = 6

24 - 6 = 18

or

24 x 0.75 = 18

This is how i do it! Take the percent and place it over 100 (100 is supposed to be the denominator!) Then you take the percent sign off of the percent number (2) and simplify to its lowest terms! Then you should have 1/50.
