How to work it out

  1. Turn the percentage into a decimal: 30 ÷ 100 = 0.3
  2. Multiply: 0.3 × 63 = 18.9
  3. Check: Work backwards: 18.9 ÷ 63 × 100 = 30%.

Another method. As a proportion of part to whole: 30/100 = part/63, so part = 30 × 63 ÷ 100 = 18.9. Both methods always give the same answer.

In a spreadsheet: =30%*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

18.9 is the 30% share of 63. The remaining 70% is 44.1, and the two parts add back up to 63.

Discounts: 30% off an item priced $63 saves $18.9, so you pay $44.1.

Adding and taking away 30%

Increasing 63 by 30% gives 81.9 and decreasing it by 30% gives 44.1. These do not cancel out: raising 63 by 30% and then lowering the result by 30% ends at 57.33, because the second 30% is taken of a bigger number.
