How to work it out
- Turn the percentage into a decimal: 64 ÷ 100 = 0.64
- Multiply: 0.64 × 30 = 19.2
- Check: Work backwards: 19.2 ÷ 30 × 100 = 64%.
Another method. As a proportion of part to whole: 64/100 = part/30, so part = 64 × 30 ÷ 100 = 19.2. Both methods always give the same answer.
In a spreadsheet: =64%*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
19.2 is the 64% share of 30. The remaining 36% is 10.8, and the two parts add back up to 30.
Discounts: 64% off an item priced $30 saves $19.2, so you pay $10.8.
Adding and taking away 64%
Increasing 30 by 64% gives 49.2 and decreasing it by 64% gives 10.8. These do not cancel out: raising 30 by 64% and then lowering the result by 64% ends at 17.712, because the second 64% is taken of a bigger number.
