How to work it out

  1. Turn the percentage into a decimal: 84 ÷ 100 = 0.84
  2. Multiply: 0.84 × 80 = 67.2
  3. Check: Work backwards: 67.2 ÷ 80 × 100 = 84%.

Another method. As a proportion of part to whole: 84/100 = part/80, so part = 84 × 80 ÷ 100 = 67.2. Both methods always give the same answer.

In a spreadsheet: =84%*80. 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

67.2 is the 84% share of 80. The remaining 16% is 12.8, and the two parts add back up to 80.

Discounts: 84% off an item priced $80 saves $67.2, so you pay $12.8.

Adding and taking away 84%

Increasing 80 by 84% gives 147.2 and decreasing it by 84% gives 12.8. These do not cancel out: raising 80 by 84% and then lowering the result by 84% ends at 23.552, because the second 84% is taken of a bigger number.
