How to work it out

  1. Turn the percentage into a decimal: 8 ÷ 100 = 0.08
  2. Multiply: 0.08 × 84 = 6.72
  3. Check: Work backwards: 6.72 ÷ 84 × 100 = 8%.

Another method. As a proportion of part to whole: 8/100 = part/84, so part = 8 × 84 ÷ 100 = 6.72. Both methods always give the same answer.

In a spreadsheet: =8%*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

6.72 is the 8% share of 84. The remaining 92% is 77.28, and the two parts add back up to 84.

Discounts: 8% off an item priced $84 saves $6.72, so you pay $77.28.

Adding and taking away 8%

Increasing 84 by 8% gives 90.72 and decreasing it by 8% gives 77.28. These do not cancel out: raising 84 by 8% and then lowering the result by 8% ends at 83.4624, because the second 8% is taken of a bigger number.
