How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 3 = 2.61
  3. Check: Work backwards: 2.61 ÷ 3 × 100 = 87%.

Another method. As a proportion of part to whole: 87/100 = part/3, so part = 87 × 3 ÷ 100 = 2.61. Both methods always give the same answer.

In a spreadsheet: =87%*3. 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

2.61 is the 87% share of 3. The remaining 13% is 0.39, and the two parts add back up to 3.

Discounts: 87% off an item priced $3 saves $2.61, so you pay $0.39.

Adding and taking away 87%

Increasing 3 by 87% gives 5.61 and decreasing it by 87% gives 0.39. These do not cancel out: raising 3 by 87% and then lowering the result by 87% ends at 0.7293, because the second 87% is taken of a bigger number.
