How to work it out

  1. Turn the percentage into a decimal: 81 ÷ 100 = 0.81
  2. Multiply: 0.81 × 63 = 51.03
  3. Check: Work backwards: 51.03 ÷ 63 × 100 = 81%.

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

In a spreadsheet: =81%*63. 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 81% share of 63. The remaining 19% is 11.97, and the two parts add back up to 63.

Discounts: 81% off an item priced $63 saves $51.03, so you pay $11.97.

Adding and taking away 81%

Increasing 63 by 81% gives 114.03 and decreasing it by 81% gives 11.97. These do not cancel out: raising 63 by 81% and then lowering the result by 81% ends at 21.6657, because the second 81% is taken of a bigger number.
