This is where you will learn how to calculate seven thousand nine hundred eighty minus eighty-seven percent (7980 minus 87 percent). We will first explain and illustrate with pictures so you get a complete understanding of what 7980 minus 87 percent means, and then we will give you the formula at the very end.

We start by showing you the image below of a dark blue box that contains 7980 of something.

7980

(100%)

87 percent means 87 per hundred, so for each hundred in 7980, you want to subtract 87. Thus, you divide 7980 by 100 and then multiply the quotient by 87 to find out how much to subtract. Here is the math to calculate how much we should subtract:

(7980 ÷ 100) × 87

= 6942.6

We made a pink square that we put on top of the image shown above to illustrate how much 87 percent is of the total 7980:

The dark blue not covered up by the pink is 7980 minus 87 percent. Thus, we simply subtract the 6942.6 from 7980 to get the answer:

7980 - 6942.6

=

**1037.4**
