The formula used to calculate 20 percent less than 644, 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 644 for OV in our formula, we get the answer to 20 percent less than 644, as solved here:
PL = 644 - ((20 ÷ 100) × 644)
PL = 644 - (0.2 × 644)
PL = 644 - 128.8
PL = 515.2
20% less than 644 = 515.2
