How to work it out

  1. Turn the percentage into a decimal: 63 ÷ 100 = 0.63
  2. Multiply: 0.63 × 81 = 51.03
  3. Check: Work backwards: 51.03 ÷ 81 × 100 = 63%.

Another method. As a proportion of part to whole: 63/100 = part/81, so part = 63 × 81 ÷ 100 = 51.03. Both methods always give the same answer.

In a spreadsheet: =63%*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

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

Discounts: 63% off an item priced $81 saves $51.03, so you pay $29.97.

Adding and taking away 63%

Increasing 81 by 63% gives 132.03 and decreasing it by 63% gives 29.97. These do not cancel out: raising 81 by 63% and then lowering the result by 63% ends at 48.8511, because the second 63% is taken of a bigger number.
