How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 68 = 21.08
  3. Check: Work backwards: 21.08 ÷ 68 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/68, so part = 31 × 68 ÷ 100 = 21.08. Both methods always give the same answer.

In a spreadsheet: =31%*68. 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

21.08 is the 31% share of 68. The remaining 69% is 46.92, and the two parts add back up to 68.

Discounts: 31% off an item priced $68 saves $21.08, so you pay $46.92.

Adding and taking away 31%

Increasing 68 by 31% gives 89.08 and decreasing it by 31% gives 46.92. These do not cancel out: raising 68 by 31% and then lowering the result by 31% ends at 61.4652, because the second 31% is taken of a bigger number.
