How to work it out

  1. Turn the percentage into a decimal: 55 ÷ 100 = 0.55
  2. Multiply: 0.55 × 40 = 22
  3. Check: Work backwards: 22 ÷ 40 × 100 = 55%.

Another method. As a proportion of part to whole: 55/100 = part/40, so part = 55 × 40 ÷ 100 = 22. Both methods always give the same answer.

In a spreadsheet: =55%*40. 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

22 is the 55% share of 40. The remaining 45% is 18, and the two parts add back up to 40.

Discounts: 55% off an item priced $40 saves $22, so you pay $18.

Adding and taking away 55%

Increasing 40 by 55% gives 62 and decreasing it by 55% gives 18. These do not cancel out: raising 40 by 55% and then lowering the result by 55% ends at 27.9, because the second 55% is taken of a bigger number.
