How to work it out
- Turn the percentage into a decimal: 99 ÷ 100 = 0.99
- Multiply: 0.99 × 80 = 79.2
- Check: Work backwards: 79.2 ÷ 80 × 100 = 99%.
Another method. As a proportion of part to whole: 99/100 = part/80, so part = 99 × 80 ÷ 100 = 79.2. Both methods always give the same answer.
In a spreadsheet: =99%*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
79.2 is the 99% share of 80. The remaining 1% is 0.8, and the two parts add back up to 80.
Discounts: 99% off an item priced $80 saves $79.2, so you pay $0.8.
Adding and taking away 99%
Increasing 80 by 99% gives 159.2 and decreasing it by 99% gives 0.8. These do not cancel out: raising 80 by 99% and then lowering the result by 99% ends at 1.592, because the second 99% is taken of a bigger number.
