How to work it out

  1. Turn the percentage into a decimal: 31 ÷ 100 = 0.31
  2. Multiply: 0.31 × 84 = 26.04
  3. Check: Work backwards: 26.04 ÷ 84 × 100 = 31%.

Another method. As a proportion of part to whole: 31/100 = part/84, so part = 31 × 84 ÷ 100 = 26.04. Both methods always give the same answer.

In a spreadsheet: =31%*84. 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

26.04 is the 31% share of 84. The remaining 69% is 57.96, and the two parts add back up to 84.

Discounts: 31% off an item priced $84 saves $26.04, so you pay $57.96.

Adding and taking away 31%

Increasing 84 by 31% gives 110.04 and decreasing it by 31% gives 57.96. These do not cancel out: raising 84 by 31% and then lowering the result by 31% ends at 75.9276, because the second 31% is taken of a bigger number.
