How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 72 = 36.72
  3. Check: Work backwards: 36.72 ÷ 72 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/72, so part = 51 × 72 ÷ 100 = 36.72. Both methods always give the same answer.

In a spreadsheet: =51%*72. 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

36.72 is the 51% share of 72. The remaining 49% is 35.28, and the two parts add back up to 72.

Discounts: 51% off an item priced $72 saves $36.72, so you pay $35.28.

Adding and taking away 51%

Increasing 72 by 51% gives 108.72 and decreasing it by 51% gives 35.28. These do not cancel out: raising 72 by 51% and then lowering the result by 51% ends at 53.2728, because the second 51% is taken of a bigger number.
