How to work it out

  1. Turn the percentage into a decimal: 22 ÷ 100 = 0.22
  2. Multiply: 0.22 × 45 = 9.9
  3. Check: Work backwards: 9.9 ÷ 45 × 100 = 22%.

Another method. As a proportion of part to whole: 22/100 = part/45, so part = 22 × 45 ÷ 100 = 9.9. Both methods always give the same answer.

In a spreadsheet: =22%*45. 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

9.9 is the 22% share of 45. The remaining 78% is 35.1, and the two parts add back up to 45.

Discounts: 22% off an item priced $45 saves $9.9, so you pay $35.1.

Adding and taking away 22%

Increasing 45 by 22% gives 54.9 and decreasing it by 22% gives 35.1. These do not cancel out: raising 45 by 22% and then lowering the result by 22% ends at 42.822, because the second 22% is taken of a bigger number.
