How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 47 = 18.8
  3. Check: Work backwards: 18.8 ÷ 47 × 100 = 40%.

Another method. As a proportion of part to whole: 40/100 = part/47, so part = 40 × 47 ÷ 100 = 18.8. Both methods always give the same answer.

In a spreadsheet: =40%*47. 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

18.8 is the 40% share of 47. The remaining 60% is 28.2, and the two parts add back up to 47.

Discounts: 40% off an item priced $47 saves $18.8, so you pay $28.2.

Adding and taking away 40%

Increasing 47 by 40% gives 65.8 and decreasing it by 40% gives 28.2. These do not cancel out: raising 47 by 40% and then lowering the result by 40% ends at 39.48, because the second 40% is taken of a bigger number.
