How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 50 = 25.5
  3. Check: Work backwards: 25.5 ÷ 50 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/50, so part = 51 × 50 ÷ 100 = 25.5. Both methods always give the same answer.

In a spreadsheet: =51%*50. 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

25.5 is the 51% share of 50. The remaining 49% is 24.5, and the two parts add back up to 50.

Discounts: 51% off an item priced $50 saves $25.5, so you pay $24.5.

Adding and taking away 51%

Increasing 50 by 51% gives 75.5 and decreasing it by 51% gives 24.5. These do not cancel out: raising 50 by 51% and then lowering the result by 51% ends at 36.995, because the second 51% is taken of a bigger number.
