How to work it out

  1. Turn the percentage into a decimal: 89 ÷ 100 = 0.89
  2. Multiply: 0.89 × 51 = 45.39
  3. Check: Work backwards: 45.39 ÷ 51 × 100 = 89%.

Another method. As a proportion of part to whole: 89/100 = part/51, so part = 89 × 51 ÷ 100 = 45.39. Both methods always give the same answer.

In a spreadsheet: =89%*51. 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

45.39 is the 89% share of 51. The remaining 11% is 5.61, and the two parts add back up to 51.

Discounts: 89% off an item priced $51 saves $45.39, so you pay $5.61.

Adding and taking away 89%

Increasing 51 by 89% gives 96.39 and decreasing it by 89% gives 5.61. These do not cancel out: raising 51 by 89% and then lowering the result by 89% ends at 10.6029, because the second 89% is taken of a bigger number.
