How to work it out

  1. Turn the percentage into a decimal: 45 ÷ 100 = 0.45
  2. Multiply: 0.45 × 47 = 21.15
  3. Check: Work backwards: 21.15 ÷ 47 × 100 = 45%.

Another method. As a proportion of part to whole: 45/100 = part/47, so part = 45 × 47 ÷ 100 = 21.15. Both methods always give the same answer.

In a spreadsheet: =45%*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

21.15 is the 45% share of 47. The remaining 55% is 25.85, and the two parts add back up to 47.

Discounts: 45% off an item priced $47 saves $21.15, so you pay $25.85.

Adding and taking away 45%

Increasing 47 by 45% gives 68.15 and decreasing it by 45% gives 25.85. These do not cancel out: raising 47 by 45% and then lowering the result by 45% ends at 37.4825, because the second 45% is taken of a bigger number.
