How to work it out

  1. Turn the percentage into a decimal: 34 ÷ 100 = 0.34
  2. Multiply: 0.34 × 80 = 27.2
  3. Check: Work backwards: 27.2 ÷ 80 × 100 = 34%.

Another method. As a proportion of part to whole: 34/100 = part/80, so part = 34 × 80 ÷ 100 = 27.2. Both methods always give the same answer.

In a spreadsheet: =34%*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

27.2 is the 34% share of 80. The remaining 66% is 52.8, and the two parts add back up to 80.

Discounts: 34% off an item priced $80 saves $27.2, so you pay $52.8.

Adding and taking away 34%

Increasing 80 by 34% gives 107.2 and decreasing it by 34% gives 52.8. These do not cancel out: raising 80 by 34% and then lowering the result by 34% ends at 70.752, because the second 34% is taken of a bigger number.
