How to work it out
- Turn the percentage into a decimal: 77 ÷ 100 = 0.77
- Multiply: 0.77 × 87 = 66.99
- Check: Work backwards: 66.99 ÷ 87 × 100 = 77%.
Another method. As a proportion of part to whole: 77/100 = part/87, so part = 77 × 87 ÷ 100 = 66.99. Both methods always give the same answer.
In a spreadsheet: =77%*87. 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
66.99 is the 77% share of 87. The remaining 23% is 20.01, and the two parts add back up to 87.

Adding and taking away 77%
Increasing 87 by 77% gives 153.99 and decreasing it by 77% gives 20.01. These do not cancel out: raising 87 by 77% and then lowering the result by 77% ends at 35.4177, because the second 77% is taken of a bigger number.
