How to work it out
- Turn the percentage into a decimal: 100 ÷ 100 = 1
- Multiply: 1 × 17 = 17
- Check: Work backwards: 17 ÷ 17 × 100 = 100%.
Another method. As a proportion of part to whole: 100/100 = part/17, so part = 100 × 17 ÷ 100 = 17. Both methods always give the same answer.
In a spreadsheet: =100%*17. 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
100% of a number is the number itself, so the answer is 17.
Mark-ups: pricing an item at 100% of its $17 cost means selling it for $17.
Adding and taking away 100%
