How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 18 = 14.04
  3. Check: Work backwards: 14.04 ÷ 18 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/18, so part = 78 × 18 ÷ 100 = 14.04. Both methods always give the same answer.

In a spreadsheet: =78%*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

14.04 is the 78% share of 18. The remaining 22% is 3.96, and the two parts add back up to 18.

Discounts: 78% off an item priced $18 saves $14.04, so you pay $3.96.

Adding and taking away 78%

Increasing 18 by 78% gives 32.04 and decreasing it by 78% gives 3.96. These do not cancel out: raising 18 by 78% and then lowering the result by 78% ends at 7.0488, because the second 78% is taken of a bigger number.
