How to work it out

  1. Turn the percentage into a decimal: 57 ÷ 100 = 0.57
  2. Multiply: 0.57 × 18 = 10.26
  3. Check: Work backwards: 10.26 ÷ 18 × 100 = 57%.

Another method. As a proportion of part to whole: 57/100 = part/18, so part = 57 × 18 ÷ 100 = 10.26. Both methods always give the same answer.

In a spreadsheet: =57%*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

10.26 is the 57% share of 18. The remaining 43% is 7.74, and the two parts add back up to 18.

Discounts: 57% off an item priced $18 saves $10.26, so you pay $7.74.

Adding and taking away 57%

Increasing 18 by 57% gives 28.26 and decreasing it by 57% gives 7.74. These do not cancel out: raising 18 by 57% and then lowering the result by 57% ends at 12.1518, because the second 57% is taken of a bigger number.
