How to work it out

  1. Turn the percentage into a decimal: 55 ÷ 100 = 0.55
  2. Multiply: 0.55 × 87 = 47.85
  3. Check: Work backwards: 47.85 ÷ 87 × 100 = 55%.

Another method. As a proportion of part to whole: 55/100 = part/87, so part = 55 × 87 ÷ 100 = 47.85. Both methods always give the same answer.

In a spreadsheet: =55%*87. 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

47.85 is the 55% share of 87. The remaining 45% is 39.15, and the two parts add back up to 87.

Discounts: 55% off an item priced $87 saves $47.85, so you pay $39.15.

Adding and taking away 55%

Increasing 87 by 55% gives 134.85 and decreasing it by 55% gives 39.15. These do not cancel out: raising 87 by 55% and then lowering the result by 55% ends at 60.6825, because the second 55% is taken of a bigger number.
