How to work it out

  1. Turn the percentage into a decimal: 63 ÷ 100 = 0.63
  2. Multiply: 0.63 × 40 = 25.2
  3. Check: Work backwards: 25.2 ÷ 40 × 100 = 63%.

Another method. As a proportion of part to whole: 63/100 = part/40, so part = 63 × 40 ÷ 100 = 25.2. Both methods always give the same answer.

In a spreadsheet: =63%*40. 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

25.2 is the 63% share of 40. The remaining 37% is 14.8, and the two parts add back up to 40.

Discounts: 63% off an item priced $40 saves $25.2, so you pay $14.8.

Adding and taking away 63%

Increasing 40 by 63% gives 65.2 and decreasing it by 63% gives 14.8. These do not cancel out: raising 40 by 63% and then lowering the result by 63% ends at 24.124, because the second 63% is taken of a bigger number.
