How to work it out

  1. Turn the percentage into a decimal: 8 ÷ 100 = 0.08
  2. Multiply: 0.08 × 18 = 1.44
  3. Check: Work backwards: 1.44 ÷ 18 × 100 = 8%.

Another method. As a proportion of part to whole: 8/100 = part/18, so part = 8 × 18 ÷ 100 = 1.44. Both methods always give the same answer.

In a spreadsheet: =8%*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

1.44 is the 8% share of 18. The remaining 92% is 16.56, and the two parts add back up to 18.

Discounts: 8% off an item priced $18 saves $1.44, so you pay $16.56.

Adding and taking away 8%

Increasing 18 by 8% gives 19.44 and decreasing it by 8% gives 16.56. These do not cancel out: raising 18 by 8% and then lowering the result by 8% ends at 17.8848, because the second 8% is taken of a bigger number.
