How to work it out
- Turn the percentage into a decimal: 28 ÷ 100 = 0.28
- Multiply: 0.28 × 1 = 0.28
- Check: Work backwards: 0.28 ÷ 1 × 100 = 28%.
Another method. As a proportion of part to whole: 28/100 = part/1, so part = 28 × 1 ÷ 100 = 0.28. Both methods always give the same answer.
In a spreadsheet: =28%*1. 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
0.28 is the 28% share of 1. The remaining 72% is 0.72, and the two parts add back up to 1.
Discounts: 28% off an item priced $1 saves $0.28, so you pay $0.72.
Adding and taking away 28%
Increasing 1 by 28% gives 1.28 and decreasing it by 28% gives 0.72. These do not cancel out: raising 1 by 28% and then lowering the result by 28% ends at 0.9216, because the second 28% is taken of a bigger number.
