How to work it out

  1. Turn the percentage into a decimal: 37 ÷ 100 = 0.37
  2. Multiply: 0.37 × 81 = 29.97
  3. Check: Work backwards: 29.97 ÷ 81 × 100 = 37%.

Another method. As a proportion of part to whole: 37/100 = part/81, so part = 37 × 81 ÷ 100 = 29.97. Both methods always give the same answer.

In a spreadsheet: =37%*81. 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

29.97 is the 37% share of 81. The remaining 63% is 51.03, and the two parts add back up to 81.

Discounts: 37% off an item priced $81 saves $29.97, so you pay $51.03.

Adding and taking away 37%

Increasing 81 by 37% gives 110.97 and decreasing it by 37% gives 51.03. These do not cancel out: raising 81 by 37% and then lowering the result by 37% ends at 69.9111, because the second 37% is taken of a bigger number.
