How to work it out

  1. Turn the percentage into a decimal: 89 ÷ 100 = 0.89
  2. Multiply: 0.89 × 20 = 17.8
  3. Check: Work backwards: 17.8 ÷ 20 × 100 = 89%.

Another method. As a proportion of part to whole: 89/100 = part/20, so part = 89 × 20 ÷ 100 = 17.8. Both methods always give the same answer.

In a spreadsheet: =89%*20. 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

17.8 is the 89% share of 20. The remaining 11% is 2.2, and the two parts add back up to 20.

Discounts: 89% off an item priced $20 saves $17.8, so you pay $2.2.

Adding and taking away 89%

Increasing 20 by 89% gives 37.8 and decreasing it by 89% gives 2.2. These do not cancel out: raising 20 by 89% and then lowering the result by 89% ends at 4.158, because the second 89% is taken of a bigger number.
