How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 22 = 2.2
  3. Check: Work backwards: 2.2 ÷ 22 × 100 = 10%.

Another method. As a proportion of part to whole: 10/100 = part/22, so part = 10 × 22 ÷ 100 = 2.2. Both methods always give the same answer.

In a spreadsheet: =10%*22. 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

2.2 is the 10% share of 22. The remaining 90% is 19.8, and the two parts add back up to 22.

Discounts: 10% off an item priced $22 saves $2.2, so you pay $19.8.

Adding and taking away 10%

Increasing 22 by 10% gives 24.2 and decreasing it by 10% gives 19.8. These do not cancel out: raising 22 by 10% and then lowering the result by 10% ends at 21.78, because the second 10% is taken of a bigger number.
