How to work it out
- Turn the percentage into a decimal: 15 ÷ 100 = 0.15
- Multiply: 0.15 × 17 = 2.55
- Check: Work backwards: 2.55 ÷ 17 × 100 = 15%.
Another method. As a proportion of part to whole: 15/100 = part/17, so part = 15 × 17 ÷ 100 = 2.55. Both methods always give the same answer.
In a spreadsheet: =15%*17. 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
2.55 is the 15% share of 17. The remaining 85% is 14.45, and the two parts add back up to 17.
Discounts: 15% off an item priced $17 saves $2.55, so you pay $14.45.
Adding and taking away 15%
Increasing 17 by 15% gives 19.55 and decreasing it by 15% gives 14.45. These do not cancel out: raising 17 by 15% and then lowering the result by 15% ends at 16.6175, because the second 15% is taken of a bigger number.
