How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 83 = 72.21
  3. Check: Work backwards: 72.21 ÷ 83 × 100 = 87%.

Another method. As a proportion of part to whole: 87/100 = part/83, so part = 87 × 83 ÷ 100 = 72.21. Both methods always give the same answer.

In a spreadsheet: =87%*83. 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

72.21 is the 87% share of 83. The remaining 13% is 10.79, and the two parts add back up to 83.

Discounts: 87% off an item priced $83 saves $72.21, so you pay $10.79.

Adding and taking away 87%

Increasing 83 by 87% gives 155.21 and decreasing it by 87% gives 10.79. These do not cancel out: raising 83 by 87% and then lowering the result by 87% ends at 20.1773, because the second 87% is taken of a bigger number.
