What is 20 percent less than 400? What is the formula used to calculate 20 percent less than 400? How can we calculate 20 percent less than 400?
Here we will show you the formula used to calculate 20 percent less than 400 (20% less than 400), and then we will calculate the answer to 20 percent less than 400 using our formula. We will also illustrate what 20 percent less than 400 looks like.
The formula used to calculate 20 percent less than 400, 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 400 for OV in our formula, we get the answer to 20 percent less than 400, as solved here:
PL = 400 - ((20 ÷ 100) × 400)
PL = 400 - (0.2 × 400)
PL = 400 - 80
PL = 320
20% less than 400 = 320
So, how does our formula work to calculate 20 percent less than 400? First, it takes 20 percent of 400, and then we subtract that result from 400 to get our final answer. We have provided an illustration below so you can better visualize 20 percent less than 400.
In our illustration above, the areas shaded in blue and red add up to 400, and the area shaded in red is 20 percent of 400. In other words, blue is 320, red is 80, and blue plus red is 400.
