How to work it out

  1. Turn the percentage into a decimal: 5 ÷ 100 = 0.05
  2. Multiply: 0.05 × 9 = 0.45
  3. Check: Work backwards: 0.45 ÷ 9 × 100 = 5%.

Another method. As a proportion of part to whole: 5/100 = part/9, so part = 5 × 9 ÷ 100 = 0.45. Both methods always give the same answer.

In a spreadsheet: =5%*9. 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

0.45 is the 5% share of 9. The remaining 95% is 8.55, and the two parts add back up to 9.

Discounts: 5% off an item priced $9 saves $0.45, so you pay $8.55.

Adding and taking away 5%

Increasing 9 by 5% gives 9.45 and decreasing it by 5% gives 8.55. These do not cancel out: raising 9 by 5% and then lowering the result by 5% ends at 8.9775, because the second 5% is taken of a bigger number.
