How to work it out

  1. Turn the percentage into a decimal: 11 ÷ 100 = 0.11
  2. Multiply: 0.11 × 18 = 1.98
  3. Check: Work backwards: 1.98 ÷ 18 × 100 = 11%.

Another method. As a proportion of part to whole: 11/100 = part/18, so part = 11 × 18 ÷ 100 = 1.98. Both methods always give the same answer.

In a spreadsheet: =11%*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

1.98 is the 11% share of 18. The remaining 89% is 16.02, and the two parts add back up to 18.

Discounts: 11% off an item priced $18 saves $1.98, so you pay $16.02.

Adding and taking away 11%

Increasing 18 by 11% gives 19.98 and decreasing it by 11% gives 16.02. These do not cancel out: raising 18 by 11% and then lowering the result by 11% ends at 17.7822, because the second 11% is taken of a bigger number.
