How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 99 = 50.49
  3. Check: Work backwards: 50.49 ÷ 99 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/99, so part = 51 × 99 ÷ 100 = 50.49. Both methods always give the same answer.

In a spreadsheet: =51%*99. 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

50.49 is the 51% share of 99. The remaining 49% is 48.51, and the two parts add back up to 99.

Discounts: 51% off an item priced $99 saves $50.49, so you pay $48.51.

Adding and taking away 51%

Increasing 99 by 51% gives 149.49 and decreasing it by 51% gives 48.51. These do not cancel out: raising 99 by 51% and then lowering the result by 51% ends at 73.2501, because the second 51% is taken of a bigger number.
