The formula used to calculate 15 percent less than 642, 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 15 for P and 642 for OV in our formula, we get the answer to 15 percent less than 642, as solved here:
PL = 642 - ((15 ÷ 100) × 642)
PL = 642 - (0.15 × 642)
PL = 642 - 96.3
PL = 545.7
15% less than 642 = 545.7
