How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 89 = 45.39
  3. Check: Work backwards: 45.39 ÷ 89 × 100 = 51%.

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

In a spreadsheet: =51%*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

45.39 is the 51% share of 89. The remaining 49% is 43.61, and the two parts add back up to 89.

Discounts: 51% off an item priced $89 saves $45.39, so you pay $43.61.

Adding and taking away 51%

Increasing 89 by 51% gives 134.39 and decreasing it by 51% gives 43.61. These do not cancel out: raising 89 by 51% and then lowering the result by 51% ends at 65.8511, because the second 51% is taken of a bigger number.
