How to work it out
- Turn the percentage into a decimal: 11 ÷ 100 = 0.11
- Multiply: 0.11 × 78 = 8.58
- Check: Work backwards: 8.58 ÷ 78 × 100 = 11%.
Another method. As a proportion of part to whole: 11/100 = part/78, so part = 11 × 78 ÷ 100 = 8.58. Both methods always give the same answer.
In a spreadsheet: =11%*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 11%
Increasing 78 by 11% gives 86.58 and decreasing it by 11% gives 69.42. These do not cancel out: raising 78 by 11% and then lowering the result by 11% ends at 77.0562, because the second 11% is taken of a bigger number.
