How to work it out

  1. Turn the percentage into a decimal: 80 ÷ 100 = 0.8
  2. Multiply: 0.8 × 89 = 71.2
  3. Check: Work backwards: 71.2 ÷ 89 × 100 = 80%.

Another method. As a proportion of part to whole: 80/100 = part/89, so part = 80 × 89 ÷ 100 = 71.2. Both methods always give the same answer.

In a spreadsheet: =80%*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

71.2 is the 80% share of 89. The remaining 20% is 17.8, and the two parts add back up to 89.

Discounts: 80% off an item priced $89 saves $71.2, so you pay $17.8.

Adding and taking away 80%

Increasing 89 by 80% gives 160.2 and decreasing it by 80% gives 17.8. These do not cancel out: raising 89 by 80% and then lowering the result by 80% ends at 32.04, because the second 80% is taken of a bigger number.
