How to work it out

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

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

In a spreadsheet: =87%*100. 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

87 is the 87% share of 100. The remaining 13% is 13, and the two parts add back up to 100.

Discounts: 87% off an item priced $100 saves $87, so you pay $13.

Adding and taking away 87%

Increasing 100 by 87% gives 187 and decreasing it by 87% gives 13. These do not cancel out: raising 100 by 87% and then lowering the result by 87% ends at 24.31, because the second 87% is taken of a bigger number.
