How to work it out
- Turn the percentage into a decimal: 8 ÷ 100 = 0.08
- Multiply: 0.08 × 78 = 6.24
- Check: Work backwards: 6.24 ÷ 78 × 100 = 8%.
Another method. As a proportion of part to whole: 8/100 = part/78, so part = 8 × 78 ÷ 100 = 6.24. Both methods always give the same answer.
In a spreadsheet: =8%*78. 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

Adding and taking away 8%
Increasing 78 by 8% gives 84.24 and decreasing it by 8% gives 71.76. These do not cancel out: raising 78 by 8% and then lowering the result by 8% ends at 77.5008, because the second 8% is taken of a bigger number.
