How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 55 = 47.85
  3. Check: Work backwards: 47.85 ÷ 55 × 100 = 87%.

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

In a spreadsheet: =87%*55. 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 87% share of 55. The remaining 13% is 7.15, and the two parts add back up to 55.

Discounts: 87% off an item priced $55 saves $47.85, so you pay $7.15.

Adding and taking away 87%

Increasing 55 by 87% gives 102.85 and decreasing it by 87% gives 7.15. These do not cancel out: raising 55 by 87% and then lowering the result by 87% ends at 13.3705, because the second 87% is taken of a bigger number.
