How to work it out

  1. Turn the percentage into a decimal: 91 ÷ 100 = 0.91
  2. Multiply: 0.91 × 51 = 46.41
  3. Check: Work backwards: 46.41 ÷ 51 × 100 = 91%.

Another method. As a proportion of part to whole: 91/100 = part/51, so part = 91 × 51 ÷ 100 = 46.41. Both methods always give the same answer.

In a spreadsheet: =91%*51. 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

46.41 is the 91% share of 51. The remaining 9% is 4.59, and the two parts add back up to 51.

Discounts: 91% off an item priced $51 saves $46.41, so you pay $4.59.

Adding and taking away 91%

Increasing 51 by 91% gives 97.41 and decreasing it by 91% gives 4.59. These do not cancel out: raising 51 by 91% and then lowering the result by 91% ends at 8.7669, because the second 91% is taken of a bigger number.
