How to work it out

  1. Turn the percentage into a decimal: 57 ÷ 100 = 0.57
  2. Multiply: 0.57 × 51 = 29.07
  3. Check: Work backwards: 29.07 ÷ 51 × 100 = 57%.

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

In a spreadsheet: =57%*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

29.07 is the 57% share of 51. The remaining 43% is 21.93, and the two parts add back up to 51.

Discounts: 57% off an item priced $51 saves $29.07, so you pay $21.93.

Adding and taking away 57%

Increasing 51 by 57% gives 80.07 and decreasing it by 57% gives 21.93. These do not cancel out: raising 51 by 57% and then lowering the result by 57% ends at 34.4301, because the second 57% is taken of a bigger number.
