What is 40 percent less than 20? What is the formula used to calculate 40 percent less than 20? How can we calculate 40 percent less than 20?

Here we will show you the formula used to calculate 40 percent less than 20 (40% less than 20), and then we will calculate the answer to 40 percent less than 20 using our formula. We will also illustrate what 40 percent less than 20 looks like.

The formula used to calculate 40 percent less than 20, 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 40 for P and 20 for OV in our formula, we get the answer to 40 percent less than 20, as solved here:

PL = 20 - ((40 ÷ 100) × 20)
PL = 20 - (0.4 × 20)
PL = 20 - 8
PL = 12
40% less than 20 = 12

So, how does our formula work to calculate 40 percent less than 20? First, it takes 40 percent of 20, and then we subtract that result from 20 to get our final answer. We have provided an illustration below so you can better visualize 40 percent less than 20.
