What is 20 percent less than 831? What is the formula used to calculate 20 percent less than 831? How can we calculate 20 percent less than 831?
Here we will show you the formula used to calculate 20 percent less than 831 (20% less than 831), and then we will calculate the answer to 20 percent less than 831 using our formula. We will also illustrate what 20 percent less than 831 looks like.
The formula used to calculate 20 percent less than 831, 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 831 for OV in our formula, we get the answer to 20 percent less than 831, as solved here:
PL = 831 - ((20 ÷ 100) × 831)
PL = 831 - (0.2 × 831)
PL = 831 - 166.2
PL = 664.8
20% less than 831 = 664.8
So, how does our formula work to calculate 20 percent less than 831? First, it takes 20 percent of 831, and then we subtract that result from 831 to get our final answer. We have provided an illustration below so you can better visualize 20 percent less than 831.
In our illustration above, the areas shaded in blue and red add up to 831, and the area shaded in red is 20 percent of 831. In other words, blue is 664.8, red is 166.2, and blue plus red is 831.
