How to work it out

  1. Turn the percentage into a decimal: 49 ÷ 100 = 0.49
  2. Multiply: 0.49 × 18 = 8.82
  3. Check: Work backwards: 8.82 ÷ 18 × 100 = 49%.

Another method. As a proportion of part to whole: 49/100 = part/18, so part = 49 × 18 ÷ 100 = 8.82. Both methods always give the same answer.

In a spreadsheet: =49%*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

8.82 is the 49% share of 18. The remaining 51% is 9.18, and the two parts add back up to 18.

Discounts: 49% off an item priced $18 saves $8.82, so you pay $9.18.

Adding and taking away 49%

Increasing 18 by 49% gives 26.82 and decreasing it by 49% gives 9.18. These do not cancel out: raising 18 by 49% and then lowering the result by 49% ends at 13.6782, because the second 49% is taken of a bigger number.
