What is 40 percent less than 31? What is the formula used to calculate 40 percent less than 31? How can we calculate 40 percent less than 31?
Here we will show you the formula used to calculate 40 percent less than 31 (40% less than 31), and then we will calculate the answer to 40 percent less than 31 using our formula. We will also illustrate what 40 percent less than 31 looks like.
The formula used to calculate 40 percent less than 31, 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 31 for OV in our formula, we get the answer to 40 percent less than 31, as solved here:
PL = 31 - ((40 ÷ 100) × 31)
PL = 31 - (0.4 × 31)
PL = 31 - 12.4
PL = 18.6
40% less than 31 = 18.6
So, how does our formula work to calculate 40 percent less than 31? First, it takes 40 percent of 31, and then we subtract that result from 31 to get our final answer. We have provided an illustration below so you can better visualize 40 percent less than 31.
In our illustration above, the areas shaded in blue and red add up to 31, and the area shaded in red is 40 percent of 31. In other words, blue is 18.6, red is 12.4, and blue plus red is 31.
