How to work it out
- Turn the percentage into a decimal: 99 ÷ 100 = 0.99
- Multiply: 0.99 × 77 = 76.23
- Check: Work backwards: 76.23 ÷ 77 × 100 = 99%.
Another method. As a proportion of part to whole: 99/100 = part/77, so part = 99 × 77 ÷ 100 = 76.23. Both methods always give the same answer.
In a spreadsheet: =99%*77. 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 99%
Increasing 77 by 99% gives 153.23 and decreasing it by 99% gives 0.77. These do not cancel out: raising 77 by 99% and then lowering the result by 99% ends at 1.5323, because the second 99% is taken of a bigger number.
