How to work it out
- Turn the percentage into a decimal: 90 ÷ 100 = 0.9
- Multiply: 0.9 × 34 = 30.6
- Check: Work backwards: 30.6 ÷ 34 × 100 = 90%.
Another method. As a proportion of part to whole: 90/100 = part/34, so part = 90 × 34 ÷ 100 = 30.6. Both methods always give the same answer.
In a spreadsheet: =90%*34. 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
30.6 is the 90% share of 34. The remaining 10% is 3.4, and the two parts add back up to 34.
Discounts: 90% off an item priced $34 saves $30.6, so you pay $3.4.
Adding and taking away 90%
Increasing 34 by 90% gives 64.6 and decreasing it by 90% gives 3.4. These do not cancel out: raising 34 by 90% and then lowering the result by 90% ends at 6.46, because the second 90% is taken of a bigger number.
