This is where you will learn how to calculate thirty-one minus one percent (31 minus 1 percent). We will first explain and illustrate with pictures so you get a complete understanding of what 31 minus 1 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 31 of something.

31

(100%)

1 percent means 1 per hundred, so for each hundred in 31, you want to subtract 1. Thus, you divide 31 by 100 and then multiply the quotient by 1 to find out how much to subtract. Here is the math to calculate how much we should subtract:

(31 ÷ 100) × 1

= 0.31

We made a pink square that we put on top of the image shown above to illustrate how much 1 percent is of the total 31:

The dark blue not covered up by the pink is 31 minus 1 percent. Thus, we simply subtract the 0.31 from 31 to get the answer:

31 - 0.31

=

**30.69**

The explanation and illustrations above are the educational way of calculating 31 minus 1 percent. You can also, of course, use formulas to calculate 31 minus 1%.

Below we show you two formulas that you can use to calculate 31 minus 1 percent and similar problems in the future.

**Formula 1**

Number - ((Number × Percent/100))

31 - ((31 × 1/100))

31 - 0.31

=

**30.69**

**Formula 2**

Number × (1 - (Percent/100))

31 × (1 - (1/100))

31 × 0.99

=

**30.69**
