How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 16 = 3.36
  3. Check: Work backwards: 3.36 ÷ 16 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/16, so part = 21 × 16 ÷ 100 = 3.36. Both methods always give the same answer.

In a spreadsheet: =21%*16. 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

3.36 is the 21% share of 16. The remaining 79% is 12.64, and the two parts add back up to 16.

Discounts: 21% off an item priced $16 saves $3.36, so you pay $12.64.

Adding and taking away 21%

Increasing 16 by 21% gives 19.36 and decreasing it by 21% gives 12.64. These do not cancel out: raising 16 by 21% and then lowering the result by 21% ends at 15.2944, because the second 21% is taken of a bigger number.
