How to work it out

  1. Turn the percentage into a decimal: 71 ÷ 100 = 0.71
  2. Multiply: 0.71 × 45 = 31.95
  3. Check: Work backwards: 31.95 ÷ 45 × 100 = 71%.

Another method. As a proportion of part to whole: 71/100 = part/45, so part = 71 × 45 ÷ 100 = 31.95. Both methods always give the same answer.

In a spreadsheet: =71%*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

31.95 is the 71% share of 45. The remaining 29% is 13.05, and the two parts add back up to 45.

Discounts: 71% off an item priced $45 saves $31.95, so you pay $13.05.

Adding and taking away 71%

Increasing 45 by 71% gives 76.95 and decreasing it by 71% gives 13.05. These do not cancel out: raising 45 by 71% and then lowering the result by 71% ends at 22.3155, because the second 71% is taken of a bigger number.
