How to work it out
- Turn the percentage into a decimal: 13 ÷ 100 = 0.13
- Multiply: 0.13 × 77 = 10.01
- Check: Work backwards: 10.01 ÷ 77 × 100 = 13%.
Another method. As a proportion of part to whole: 13/100 = part/77, so part = 13 × 77 ÷ 100 = 10.01. Both methods always give the same answer.
In a spreadsheet: =13%*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
10.01 is the 13% share of 77. The remaining 87% is 66.99, and the two parts add back up to 77.

Adding and taking away 13%
Increasing 77 by 13% gives 87.01 and decreasing it by 13% gives 66.99. These do not cancel out: raising 77 by 13% and then lowering the result by 13% ends at 75.6987, because the second 13% is taken of a bigger number.
