How to work it out

  1. Turn the percentage into a decimal: 1 ÷ 100 = 0.01
  2. Multiply: 0.01 × 51 = 0.51
  3. Check: Work backwards: 0.51 ÷ 51 × 100 = 1%.

Another method. As a proportion of part to whole: 1/100 = part/51, so part = 1 × 51 ÷ 100 = 0.51. Both methods always give the same answer.

In a spreadsheet: =1%*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

0.51 is the 1% share of 51. The remaining 99% is 50.49, and the two parts add back up to 51.

Discounts: 1% off an item priced $51 saves $0.51, so you pay $50.49.

Adding and taking away 1%

Increasing 51 by 1% gives 51.51 and decreasing it by 1% gives 50.49. These do not cancel out: raising 51 by 1% and then lowering the result by 1% ends at 50.9949, because the second 1% is taken of a bigger number.
