How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 65 = 13.65
  3. Check: Work backwards: 13.65 ÷ 65 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/65, so part = 21 × 65 ÷ 100 = 13.65. Both methods always give the same answer.

In a spreadsheet: =21%*65. 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

13.65 is the 21% share of 65. The remaining 79% is 51.35, and the two parts add back up to 65.

Discounts: 21% off an item priced $65 saves $13.65, so you pay $51.35.

Adding and taking away 21%

Increasing 65 by 21% gives 78.65 and decreasing it by 21% gives 51.35. These do not cancel out: raising 65 by 21% and then lowering the result by 21% ends at 62.1335, because the second 21% is taken of a bigger number.
