How to work it out

  1. Turn the percentage into a decimal: 25 ÷ 100 = 0.25
  2. Multiply: 0.25 × 51 = 12.75
  3. Check: Work backwards: 12.75 ÷ 51 × 100 = 25%.

Another method. As a proportion of part to whole: 25/100 = part/51, so part = 25 × 51 ÷ 100 = 12.75. Both methods always give the same answer.

In a spreadsheet: =25%*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

12.75 is the 25% share of 51. The remaining 75% is 38.25, and the two parts add back up to 51.

Discounts: 25% off an item priced $51 saves $12.75, so you pay $38.25.

Adding and taking away 25%

Increasing 51 by 25% gives 63.75 and decreasing it by 25% gives 38.25. These do not cancel out: raising 51 by 25% and then lowering the result by 25% ends at 47.8125, because the second 25% is taken of a bigger number.
