How to work it out

  1. Turn the percentage into a decimal: 15 ÷ 100 = 0.15
  2. Multiply: 0.15 × 5 = 0.75
  3. Check: Work backwards: 0.75 ÷ 5 × 100 = 15%.

Another method. As a proportion of part to whole: 15/100 = part/5, so part = 15 × 5 ÷ 100 = 0.75. Both methods always give the same answer.

In a spreadsheet: =15%*5. 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

0.75 is the 15% share of 5. The remaining 85% is 4.25, and the two parts add back up to 5.

Discounts: 15% off an item priced $5 saves $0.75, so you pay $4.25.

Adding and taking away 15%

Increasing 5 by 15% gives 5.75 and decreasing it by 15% gives 4.25. These do not cancel out: raising 5 by 15% and then lowering the result by 15% ends at 4.8875, because the second 15% is taken of a bigger number.
