How to work it out

  1. Turn the percentage into a decimal: 43 ÷ 100 = 0.43
  2. Multiply: 0.43 × 81 = 34.83
  3. Check: Work backwards: 34.83 ÷ 81 × 100 = 43%.

Another method. As a proportion of part to whole: 43/100 = part/81, so part = 43 × 81 ÷ 100 = 34.83. Both methods always give the same answer.

In a spreadsheet: =43%*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

34.83 is the 43% share of 81. The remaining 57% is 46.17, and the two parts add back up to 81.

Discounts: 43% off an item priced $81 saves $34.83, so you pay $46.17.

Adding and taking away 43%

Increasing 81 by 43% gives 115.83 and decreasing it by 43% gives 46.17. These do not cancel out: raising 81 by 43% and then lowering the result by 43% ends at 66.0231, because the second 43% is taken of a bigger number.
