How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 63 = 6.3
  3. Check: Work backwards: 6.3 ÷ 63 × 100 = 10%.

Another method. As a proportion of part to whole: 10/100 = part/63, so part = 10 × 63 ÷ 100 = 6.3. Both methods always give the same answer.

In a spreadsheet: =10%*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

6.3 is the 10% share of 63. The remaining 90% is 56.7, and the two parts add back up to 63.

Discounts: 10% off an item priced $63 saves $6.3, so you pay $56.7.

Adding and taking away 10%

Increasing 63 by 10% gives 69.3 and decreasing it by 10% gives 56.7. These do not cancel out: raising 63 by 10% and then lowering the result by 10% ends at 62.37, because the second 10% is taken of a bigger number.
