How to work it out

  1. Turn the percentage into a decimal: 52 ÷ 100 = 0.52
  2. Multiply: 0.52 × 40 = 20.8
  3. Check: Work backwards: 20.8 ÷ 40 × 100 = 52%.

Another method. As a proportion of part to whole: 52/100 = part/40, so part = 52 × 40 ÷ 100 = 20.8. Both methods always give the same answer.

In a spreadsheet: =52%*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

20.8 is the 52% share of 40. The remaining 48% is 19.2, and the two parts add back up to 40.

Discounts: 52% off an item priced $40 saves $20.8, so you pay $19.2.

Adding and taking away 52%

Increasing 40 by 52% gives 60.8 and decreasing it by 52% gives 19.2. These do not cancel out: raising 40 by 52% and then lowering the result by 52% ends at 29.184, because the second 52% is taken of a bigger number.
