How to work it out
- Turn the percentage into a decimal: 70 ÷ 100 = 0.7
- Multiply: 0.7 × 77 = 53.9
- Check: Work backwards: 53.9 ÷ 77 × 100 = 70%.
Another method. As a proportion of part to whole: 70/100 = part/77, so part = 70 × 77 ÷ 100 = 53.9. Both methods always give the same answer.
In a spreadsheet: =70%*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
53.9 is the 70% share of 77. The remaining 30% is 23.1, and the two parts add back up to 77.

Adding and taking away 70%
Increasing 77 by 70% gives 130.9 and decreasing it by 70% gives 23.1. These do not cancel out: raising 77 by 70% and then lowering the result by 70% ends at 39.27, because the second 70% is taken of a bigger number.
