How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 8 = 6.24
  3. Check: Work backwards: 6.24 ÷ 8 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/8, so part = 78 × 8 ÷ 100 = 6.24. Both methods always give the same answer.

In a spreadsheet: =78%*8. 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

6.24 is the 78% share of 8. The remaining 22% is 1.76, and the two parts add back up to 8.

Discounts: 78% off an item priced $8 saves $6.24, so you pay $1.76.

Adding and taking away 78%

Increasing 8 by 78% gives 14.24 and decreasing it by 78% gives 1.76. These do not cancel out: raising 8 by 78% and then lowering the result by 78% ends at 3.1328, because the second 78% is taken of a bigger number.
