How to work it out

  1. Turn the percentage into a decimal: 2 ÷ 100 = 0.02
  2. Multiply: 0.02 × 51 = 1.02
  3. Check: Work backwards: 1.02 ÷ 51 × 100 = 2%.

Another method. As a proportion of part to whole: 2/100 = part/51, so part = 2 × 51 ÷ 100 = 1.02. Both methods always give the same answer.

In a spreadsheet: =2%*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

1.02 is the 2% share of 51. The remaining 98% is 49.98, and the two parts add back up to 51.

Discounts: 2% off an item priced $51 saves $1.02, so you pay $49.98.

Adding and taking away 2%

Increasing 51 by 2% gives 52.02 and decreasing it by 2% gives 49.98. These do not cancel out: raising 51 by 2% and then lowering the result by 2% ends at 50.9796, because the second 2% is taken of a bigger number.
