How to work it out

  1. Turn the percentage into a decimal: 89 ÷ 100 = 0.89
  2. Multiply: 0.89 × 30 = 26.7
  3. Check: Work backwards: 26.7 ÷ 30 × 100 = 89%.

Another method. As a proportion of part to whole: 89/100 = part/30, so part = 89 × 30 ÷ 100 = 26.7. Both methods always give the same answer.

In a spreadsheet: =89%*30. 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

26.7 is the 89% share of 30. The remaining 11% is 3.3, and the two parts add back up to 30.

Discounts: 89% off an item priced $30 saves $26.7, so you pay $3.3.

Adding and taking away 89%

Increasing 30 by 89% gives 56.7 and decreasing it by 89% gives 3.3. These do not cancel out: raising 30 by 89% and then lowering the result by 89% ends at 6.237, because the second 89% is taken of a bigger number.
