How to work it out
- Turn the percentage into a decimal: 50 ÷ 100 = 0.5
- Multiply: 0.5 × 1 = 0.5
- Check: Work backwards: 0.5 ÷ 1 × 100 = 50%.
Another method. As a proportion of part to whole: 50/100 = part/1, so part = 50 × 1 ÷ 100 = 0.5. Both methods always give the same answer.
In a spreadsheet: =50%*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
0.5 is the 50% share of 1. The remaining 50% is 0.5, and the two parts add back up to 1.
Discounts: 50% off an item priced $1 saves $0.5, so you pay $0.5.
Adding and taking away 50%
Increasing 1 by 50% gives 1.5 and decreasing it by 50% gives 0.5. These do not cancel out: raising 1 by 50% and then lowering the result by 50% ends at 0.75, because the second 50% is taken of a bigger number.
