How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 32 = 6.72
  3. Check: Work backwards: 6.72 ÷ 32 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/32, so part = 21 × 32 ÷ 100 = 6.72. Both methods always give the same answer.

In a spreadsheet: =21%*32. 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

6.72 is the 21% share of 32. The remaining 79% is 25.28, and the two parts add back up to 32.

Discounts: 21% off an item priced $32 saves $6.72, so you pay $25.28.

Adding and taking away 21%

Increasing 32 by 21% gives 38.72 and decreasing it by 21% gives 25.28. These do not cancel out: raising 32 by 21% and then lowering the result by 21% ends at 30.5888, because the second 21% is taken of a bigger number.
