How to work it out
- Turn the percentage into a decimal: 100 ÷ 100 = 1
- Multiply: 1 × 28 = 28
- Check: Work backwards: 28 ÷ 28 × 100 = 100%.
Another method. As a proportion of part to whole: 100/100 = part/28, so part = 100 × 28 ÷ 100 = 28. Both methods always give the same answer.
In a spreadsheet: =100%*28. 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 28.
Mark-ups: pricing an item at 100% of its $28 cost means selling it for $28.
Adding and taking away 100%
Increasing 28 by 100% gives 56. These do not cancel out: raising 28 by 100% and then lowering the result by 100% ends at 0, because the second 100% is taken of a bigger number.
