How to work it out
- Turn the percentage into a decimal: 27 ÷ 100 = 0.27
- Multiply: 0.27 × 78 = 21.06
- Check: Work backwards: 21.06 ÷ 78 × 100 = 27%.
Another method. As a proportion of part to whole: 27/100 = part/78, so part = 27 × 78 ÷ 100 = 21.06. Both methods always give the same answer.
In a spreadsheet: =27%*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 27%
Increasing 78 by 27% gives 99.06 and decreasing it by 27% gives 56.94. These do not cancel out: raising 78 by 27% and then lowering the result by 27% ends at 72.3138, because the second 27% is taken of a bigger number.
