How to work it out

  1. Turn the percentage into a decimal: 45 ÷ 100 = 0.45
  2. Multiply: 0.45 × 89 = 40.05
  3. Check: Work backwards: 40.05 ÷ 89 × 100 = 45%.

Another method. As a proportion of part to whole: 45/100 = part/89, so part = 45 × 89 ÷ 100 = 40.05. Both methods always give the same answer.

In a spreadsheet: =45%*89. 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

40.05 is the 45% share of 89. The remaining 55% is 48.95, and the two parts add back up to 89.

Discounts: 45% off an item priced $89 saves $40.05, so you pay $48.95.

Adding and taking away 45%

Increasing 89 by 45% gives 129.05 and decreasing it by 45% gives 48.95. These do not cancel out: raising 89 by 45% and then lowering the result by 45% ends at 70.9775, because the second 45% is taken of a bigger number.
