How to work it out

  1. Turn the percentage into a decimal: 65 ÷ 100 = 0.65
  2. Multiply: 0.65 × 18 = 11.7
  3. Check: Work backwards: 11.7 ÷ 18 × 100 = 65%.

Another method. As a proportion of part to whole: 65/100 = part/18, so part = 65 × 18 ÷ 100 = 11.7. Both methods always give the same answer.

In a spreadsheet: =65%*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

11.7 is the 65% share of 18. The remaining 35% is 6.3, and the two parts add back up to 18.

Discounts: 65% off an item priced $18 saves $11.7, so you pay $6.3.

Adding and taking away 65%

Increasing 18 by 65% gives 29.7 and decreasing it by 65% gives 6.3. These do not cancel out: raising 18 by 65% and then lowering the result by 65% ends at 10.395, because the second 65% is taken of a bigger number.
