How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 89 = 16.02
  3. Check: Work backwards: 16.02 ÷ 89 × 100 = 18%.

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

In a spreadsheet: =18%*89. 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 18% share of 89. The remaining 82% is 72.98, and the two parts add back up to 89.

Discounts: 18% off an item priced $89 saves $16.02, so you pay $72.98.

Adding and taking away 18%

Increasing 89 by 18% gives 105.02 and decreasing it by 18% gives 72.98. These do not cancel out: raising 89 by 18% and then lowering the result by 18% ends at 86.1164, because the second 18% is taken of a bigger number.
