How to work it out
- Turn the percentage into a decimal: 13 ÷ 100 = 0.13
- Multiply: 0.13 × 18 = 2.34
- Check: Work backwards: 2.34 ÷ 18 × 100 = 13%.
Another method. As a proportion of part to whole: 13/100 = part/18, so part = 13 × 18 ÷ 100 = 2.34. Both methods always give the same answer.
In a spreadsheet: =13%*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
2.34 is the 13% share of 18. The remaining 87% is 15.66, and the two parts add back up to 18.
Discounts: 13% off an item priced $18 saves $2.34, so you pay $15.66.
Adding and taking away 13%
Increasing 18 by 13% gives 20.34 and decreasing it by 13% gives 15.66. These do not cancel out: raising 18 by 13% and then lowering the result by 13% ends at 17.6958, because the second 13% is taken of a bigger number.
