How to work it out

  1. Turn the percentage into a decimal: 89 ÷ 100 = 0.89
  2. Multiply: 0.89 × 18 = 16.02
  3. Check: Work backwards: 16.02 ÷ 18 × 100 = 89%.

Another method. As a proportion of part to whole: 89/100 = part/18, so part = 89 × 18 ÷ 100 = 16.02. Both methods always give the same answer.

In a spreadsheet: =89%*18. 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

16.02 is the 89% share of 18. The remaining 11% is 1.98, and the two parts add back up to 18.

Discounts: 89% off an item priced $18 saves $16.02, so you pay $1.98.

Adding and taking away 89%

Increasing 18 by 89% gives 34.02 and decreasing it by 89% gives 1.98. These do not cancel out: raising 18 by 89% and then lowering the result by 89% ends at 3.7422, because the second 89% is taken of a bigger number.
