The formula used to calculate 20 percent less than 289, 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 289 for OV in our formula, we get the answer to 20 percent less than 289, as solved here:
PL = 289 - ((20 ÷ 100) × 289)
PL = 289 - (0.2 × 289)
PL = 289 - 57.8
PL = 231.2
20% less than 289 = 231.2
