How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 52 = 20.8
  3. Check: Work backwards: 20.8 ÷ 52 × 100 = 40%.

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

In a spreadsheet: =40%*52. 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 40% share of 52. The remaining 60% is 31.2, and the two parts add back up to 52.

Discounts: 40% off an item priced $52 saves $20.8, so you pay $31.2.

Adding and taking away 40%

Increasing 52 by 40% gives 72.8 and decreasing it by 40% gives 31.2. These do not cancel out: raising 52 by 40% and then lowering the result by 40% ends at 43.68, because the second 40% is taken of a bigger number.
