9.9

How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 9 = 0.9
  3. Check: Work backwards: 0.9 ÷ 9 × 100 = 10%.

In a spreadsheet: =10%*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

0.9 is the 10% share of 9. The remaining 90% is 8.1, and the two parts add back up to 9.

Discounts: 10% off an item priced $9 saves $0.9, so you pay $8.1.

Adding and taking away 10%

Increasing 9 by 10% gives 9.9 and decreasing it by 10% gives 8.1. These do not cancel out: raising 9 by 10% and then lowering the result by 10% ends at 8.91, because the second 10% is taken of a bigger number.
