How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 25 = 5.25
  3. Check: Work backwards: 5.25 ÷ 25 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/25, so part = 21 × 25 ÷ 100 = 5.25. Both methods always give the same answer.

In a spreadsheet: =21%*25. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

5.25 is the 21% share of 25. The remaining 79% is 19.75, and the two parts add back up to 25.

Discounts: 21% off an item priced $25 saves $5.25, so you pay $19.75.

Adding and taking away 21%

Increasing 25 by 21% gives 30.25 and decreasing it by 21% gives 19.75. These do not cancel out: raising 25 by 21% and then lowering the result by 21% ends at 23.8975, because the second 21% is taken of a bigger number.
