How to work it out
- Turn the percentage into a decimal: 51 ÷ 100 = 0.51
- Multiply: 0.51 × 55 = 28.05
- Check: Work backwards: 28.05 ÷ 55 × 100 = 51%.
Another method. As a proportion of part to whole: 51/100 = part/55, so part = 51 × 55 ÷ 100 = 28.05. Both methods always give the same answer.
In a spreadsheet: =51%*55. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

Adding and taking away 51%
Increasing 55 by 51% gives 83.05 and decreasing it by 51% gives 26.95. These do not cancel out: raising 55 by 51% and then lowering the result by 51% ends at 40.6945, because the second 51% is taken of a bigger number.
