How to work it out
- Turn the percentage into a decimal: 40 ÷ 100 = 0.4
- Multiply: 0.4 × 5 = 2
- Check: Work backwards: 2 ÷ 5 × 100 = 40%.
Another method. As a proportion of part to whole: 40/100 = part/5, so part = 40 × 5 ÷ 100 = 2. Both methods always give the same answer.
In a spreadsheet: =40%*5. 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
2 is the 40% share of 5. The remaining 60% is 3, and the two parts add back up to 5.
Discounts: 40% off an item priced $5 saves $2, so you pay $3.
Adding and taking away 40%
Increasing 5 by 40% gives 7 and decreasing it by 40% gives 3. These do not cancel out: raising 5 by 40% and then lowering the result by 40% ends at 4.2, because the second 40% is taken of a bigger number.
