How to work it out

  1. Turn the percentage into a decimal: 47 ÷ 100 = 0.47
  2. Multiply: 0.47 × 45 = 21.15
  3. Check: Work backwards: 21.15 ÷ 45 × 100 = 47%.

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

In a spreadsheet: =47%*45. 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 47% share of 45. The remaining 53% is 23.85, and the two parts add back up to 45.

Discounts: 47% off an item priced $45 saves $21.15, so you pay $23.85.

Adding and taking away 47%

Increasing 45 by 47% gives 66.15 and decreasing it by 47% gives 23.85. These do not cancel out: raising 45 by 47% and then lowering the result by 47% ends at 35.0595, because the second 47% is taken of a bigger number.
