How to work it out
- Turn the percentage into a decimal: 17 ÷ 100 = 0.17
- Multiply: 0.17 × 18 = 3.06
- Check: Work backwards: 3.06 ÷ 18 × 100 = 17%.
Another method. As a proportion of part to whole: 17/100 = part/18, so part = 17 × 18 ÷ 100 = 3.06. Both methods always give the same answer.
In a spreadsheet: =17%*18. 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
3.06 is the 17% share of 18. The remaining 83% is 14.94, and the two parts add back up to 18.

Adding and taking away 17%
Increasing 18 by 17% gives 21.06 and decreasing it by 17% gives 14.94. These do not cancel out: raising 18 by 17% and then lowering the result by 17% ends at 17.4798, because the second 17% is taken of a bigger number.
