How to work it out
- Turn the percentage into a decimal: 100 ÷ 100 = 1
- Multiply: 1 × 77 = 77
- Check: Work backwards: 77 ÷ 77 × 100 = 100%.
Another method. As a proportion of part to whole: 100/100 = part/77, so part = 100 × 77 ÷ 100 = 77. Both methods always give the same answer.
In a spreadsheet: =100%*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 100%
