How to work it out

  1. Turn the percentage into a decimal: 51 ÷ 100 = 0.51
  2. Multiply: 0.51 × 57 = 29.07
  3. Check: Work backwards: 29.07 ÷ 57 × 100 = 51%.

Another method. As a proportion of part to whole: 51/100 = part/57, so part = 51 × 57 ÷ 100 = 29.07. Both methods always give the same answer.

In a spreadsheet: =51%*57. 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

29.07 is the 51% share of 57. The remaining 49% is 27.93, and the two parts add back up to 57.

Discounts: 51% off an item priced $57 saves $29.07, so you pay $27.93.

Adding and taking away 51%

Increasing 57 by 51% gives 86.07 and decreasing it by 51% gives 27.93. These do not cancel out: raising 57 by 51% and then lowering the result by 51% ends at 42.1743, because the second 51% is taken of a bigger number.
