The formula used to calculate 20 percent less than 398, as well as other percent less than problems, can be seen below:
PL = OV - ((P ÷ 100) × OV)
PL (Percent Less) is the answer we want, P (%) is the percent, and OV (Original Value) is the starting value. Therefore, when we substitute 20 for P and 398 for OV in our formula, we get the answer to 20 percent less than 398, as solved here:
PL = 398 - ((20 ÷ 100) × 398)
PL = 398 - (0.2 × 398)
PL = 398 - 79.6
PL = 318.4
20% less than 398 = 318.4
