How to work it out
- Turn the percentage into a decimal: 89 ÷ 100 = 0.89
- Multiply: 0.89 × 80 = 71.2
- Check: Work backwards: 71.2 ÷ 80 × 100 = 89%.
Another method. As a proportion of part to whole: 89/100 = part/80, so part = 89 × 80 ÷ 100 = 71.2. Both methods always give the same answer.
In a spreadsheet: =89%*80. 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 89% share of 80. The remaining 11% is 8.8, and the two parts add back up to 80.
Discounts: 89% off an item priced $80 saves $71.2, so you pay $8.8.
Adding and taking away 89%
Increasing 80 by 89% gives 151.2 and decreasing it by 89% gives 8.8. These do not cancel out: raising 80 by 89% and then lowering the result by 89% ends at 16.632, because the second 89% is taken of a bigger number.
