How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 78 = 14.04
  3. Check: Work backwards: 14.04 ÷ 78 × 100 = 18%.

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

In a spreadsheet: =18%*78. 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 18% share of 78. The remaining 82% is 63.96, and the two parts add back up to 78.

Discounts: 18% off an item priced $78 saves $14.04, so you pay $63.96.

Adding and taking away 18%

Increasing 78 by 18% gives 92.04 and decreasing it by 18% gives 63.96. These do not cancel out: raising 78 by 18% and then lowering the result by 18% ends at 75.4728, because the second 18% is taken of a bigger number.
