How to work it out

  1. Turn the percentage into a decimal: 91 ÷ 100 = 0.91
  2. Multiply: 0.91 × 55 = 50.05
  3. Check: Work backwards: 50.05 ÷ 55 × 100 = 91%.

Another method. As a proportion of part to whole: 91/100 = part/55, so part = 91 × 55 ÷ 100 = 50.05. Both methods always give the same answer.

In a spreadsheet: =91%*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

50.05 is the 91% share of 55. The remaining 9% is 4.95, and the two parts add back up to 55.

Discounts: 91% off an item priced $55 saves $50.05, so you pay $4.95.

Adding and taking away 91%

Increasing 55 by 91% gives 105.05 and decreasing it by 91% gives 4.95. These do not cancel out: raising 55 by 91% and then lowering the result by 91% ends at 9.4545, because the second 91% is taken of a bigger number.
