How to work it out
- Turn the percentage into a decimal: 50 ÷ 100 = 0.5
- Multiply: 0.5 × 3 = 1.5
- Check: Work backwards: 1.5 ÷ 3 × 100 = 50%.
Another method. As a proportion of part to whole: 50/100 = part/3, so part = 50 × 3 ÷ 100 = 1.5. Both methods always give the same answer.
In a spreadsheet: =50%*3. 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
1.5 is the 50% share of 3. The remaining 50% is 1.5, and the two parts add back up to 3.
Discounts: 50% off an item priced $3 saves $1.5, so you pay $1.5.
Adding and taking away 50%
Increasing 3 by 50% gives 4.5 and decreasing it by 50% gives 1.5. These do not cancel out: raising 3 by 50% and then lowering the result by 50% ends at 2.25, because the second 50% is taken of a bigger number.
