How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 13 = 2.34
  3. Check: Work backwards: 2.34 ÷ 13 × 100 = 18%.

Another method. As a proportion of part to whole: 18/100 = part/13, so part = 18 × 13 ÷ 100 = 2.34. Both methods always give the same answer.

In a spreadsheet: =18%*13. 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 18% share of 13. The remaining 82% is 10.66, and the two parts add back up to 13.

Discounts: 18% off an item priced $13 saves $2.34, so you pay $10.66.

Adding and taking away 18%

Increasing 13 by 18% gives 15.34 and decreasing it by 18% gives 10.66. These do not cancel out: raising 13 by 18% and then lowering the result by 18% ends at 12.5788, because the second 18% is taken of a bigger number.
