How to work it out

  1. Turn the percentage into a decimal: 18 ÷ 100 = 0.18
  2. Multiply: 0.18 × 71 = 12.78
  3. Check: Work backwards: 12.78 ÷ 71 × 100 = 18%.

Another method. As a proportion of part to whole: 18/100 = part/71, so part = 18 × 71 ÷ 100 = 12.78. Both methods always give the same answer.

In a spreadsheet: =18%*71. 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

12.78 is the 18% share of 71. The remaining 82% is 58.22, and the two parts add back up to 71.

Discounts: 18% off an item priced $71 saves $12.78, so you pay $58.22.

Adding and taking away 18%

Increasing 71 by 18% gives 83.78 and decreasing it by 18% gives 58.22. These do not cancel out: raising 71 by 18% and then lowering the result by 18% ends at 68.6996, because the second 18% is taken of a bigger number.
