How to work it out

  1. Turn the percentage into a decimal: 72 ÷ 100 = 0.72
  2. Multiply: 0.72 × 51 = 36.72
  3. Check: Work backwards: 36.72 ÷ 51 × 100 = 72%.

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

In a spreadsheet: =72%*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

36.72 is the 72% share of 51. The remaining 28% is 14.28, and the two parts add back up to 51.

Discounts: 72% off an item priced $51 saves $36.72, so you pay $14.28.

Adding and taking away 72%

Increasing 51 by 72% gives 87.72 and decreasing it by 72% gives 14.28. These do not cancel out: raising 51 by 72% and then lowering the result by 72% ends at 24.5616, because the second 72% is taken of a bigger number.
