What is 20 percent less than 155? What is the formula used to calculate 20 percent less than 155? How can we calculate 20 percent less than 155?
Here we will show you the formula used to calculate 20 percent less than 155 (20% less than 155), and then we will calculate the answer to 20 percent less than 155 using our formula. We will also illustrate what 20 percent less than 155 looks like.
The formula used to calculate 20 percent less than 155, 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 155 for OV in our formula, we get the answer to 20 percent less than 155, as solved here:
PL = 155 - ((20 ÷ 100) × 155)
PL = 155 - (0.2 × 155)
PL = 155 - 31
PL = 124
20% less than 155 = 124
So, how does our formula work to calculate 20 percent less than 155? First, it takes 20 percent of 155, and then we subtract that result from 155 to get our final answer. We have provided an illustration below so you can better visualize 20 percent less than 155.
In our illustration above, the areas shaded in blue and red add up to 155, and the area shaded in red is 20 percent of 155. In other words, blue is 124, red is 31, and blue plus red is 155.
