How to work it out

  1. Turn the percentage into a decimal: 33 ÷ 100 = 0.33
  2. Multiply: 0.33 × 51 = 16.83
  3. Check: Work backwards: 16.83 ÷ 51 × 100 = 33%.

Another method. As a proportion of part to whole: 33/100 = part/51, so part = 33 × 51 ÷ 100 = 16.83. Both methods always give the same answer.

In a spreadsheet: =33%*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

16.83 is the 33% share of 51. The remaining 67% is 34.17, and the two parts add back up to 51.

Discounts: 33% off an item priced $51 saves $16.83, so you pay $34.17.

Adding and taking away 33%

Increasing 51 by 33% gives 67.83 and decreasing it by 33% gives 34.17. These do not cancel out: raising 51 by 33% and then lowering the result by 33% ends at 45.4461, because the second 33% is taken of a bigger number.
