How to work it out
- Turn the percentage into a decimal: 68 ÷ 100 = 0.68
- Multiply: 0.68 × 30 = 20.4
- Check: Work backwards: 20.4 ÷ 30 × 100 = 68%.
Another method. As a proportion of part to whole: 68/100 = part/30, so part = 68 × 30 ÷ 100 = 20.4. Both methods always give the same answer.
In a spreadsheet: =68%*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
20.4 is the 68% share of 30. The remaining 32% is 9.6, and the two parts add back up to 30.
Discounts: 68% off an item priced $30 saves $20.4, so you pay $9.6.
Adding and taking away 68%
Increasing 30 by 68% gives 50.4 and decreasing it by 68% gives 9.6. These do not cancel out: raising 30 by 68% and then lowering the result by 68% ends at 16.128, because the second 68% is taken of a bigger number.
