How to work it out

  1. Turn the percentage into a decimal: 32 ÷ 100 = 0.32
  2. Multiply: 0.32 × 40 = 12.8
  3. Check: Work backwards: 12.8 ÷ 40 × 100 = 32%.

Another method. As a proportion of part to whole: 32/100 = part/40, so part = 32 × 40 ÷ 100 = 12.8. Both methods always give the same answer.

In a spreadsheet: =32%*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

12.8 is the 32% share of 40. The remaining 68% is 27.2, and the two parts add back up to 40.

Discounts: 32% off an item priced $40 saves $12.8, so you pay $27.2.

Adding and taking away 32%

Increasing 40 by 32% gives 52.8 and decreasing it by 32% gives 27.2. These do not cancel out: raising 40 by 32% and then lowering the result by 32% ends at 35.904, because the second 32% is taken of a bigger number.
