How to work it out
- Turn the percentage into a decimal: 78 ÷ 100 = 0.78
- Multiply: 0.78 × 91 = 70.98
- Check: Work backwards: 70.98 ÷ 91 × 100 = 78%.
Another method. As a proportion of part to whole: 78/100 = part/91, so part = 78 × 91 ÷ 100 = 70.98. Both methods always give the same answer.
In a spreadsheet: =78%*91. 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
70.98 is the 78% share of 91. The remaining 22% is 20.02, and the two parts add back up to 91.

Adding and taking away 78%
Increasing 91 by 78% gives 161.98 and decreasing it by 78% gives 20.02. These do not cancel out: raising 91 by 78% and then lowering the result by 78% ends at 35.6356, because the second 78% is taken of a bigger number.
