How to work it out
- Turn the percentage into a decimal: 12 ÷ 100 = 0.12
- Multiply: 0.12 × 30 = 3.6
- Check: Work backwards: 3.6 ÷ 30 × 100 = 12%.
Another method. As a proportion of part to whole: 12/100 = part/30, so part = 12 × 30 ÷ 100 = 3.6. Both methods always give the same answer.
In a spreadsheet: =12%*30. 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
3.6 is the 12% share of 30. The remaining 88% is 26.4, and the two parts add back up to 30.
Discounts: 12% off an item priced $30 saves $3.6, so you pay $26.4.
Adding and taking away 12%
Increasing 30 by 12% gives 33.6 and decreasing it by 12% gives 26.4. These do not cancel out: raising 30 by 12% and then lowering the result by 12% ends at 29.568, because the second 12% is taken of a bigger number.
