The formula used to calculate 80 percent less than 489, 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 80 for P and 489 for OV in our formula, we get the answer to 80 percent less than 489, as solved here:
PL = 489 - ((80 ÷ 100) × 489)
PL = 489 - (0.8 × 489)
PL = 489 - 391.2
PL = 97.8
80% less than 489 = 97.8
So, how does our formula work to calculate 80 percent less than 489? First, it takes 80 percent of 489, and then we subtract that result from 489 to get our final answer. We have provided an illustration below so you can better visualize 80 percent less than 489.
