How to work it out
- Turn the percentage into a decimal: 15 ÷ 100 = 0.15
- Multiply: 0.15 × 3 = 0.45
- Check: Work backwards: 0.45 ÷ 3 × 100 = 15%.
Another method. As a proportion of part to whole: 15/100 = part/3, so part = 15 × 3 ÷ 100 = 0.45. Both methods always give the same answer.
In a spreadsheet: =15%*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
0.45 is the 15% share of 3. The remaining 85% is 2.55, and the two parts add back up to 3.
Discounts: 15% off an item priced $3 saves $0.45, so you pay $2.55.
Adding and taking away 15%
Increasing 3 by 15% gives 3.45 and decreasing it by 15% gives 2.55. These do not cancel out: raising 3 by 15% and then lowering the result by 15% ends at 2.9325, because the second 15% is taken of a bigger number.
