How to work it out
- Turn the percentage into a decimal: 21 ÷ 100 = 0.21
- Multiply: 0.21 × 58 = 12.18
- Check: Work backwards: 12.18 ÷ 58 × 100 = 21%.
Another method. As a proportion of part to whole: 21/100 = part/58, so part = 21 × 58 ÷ 100 = 12.18. Both methods always give the same answer.
In a spreadsheet: =21%*58. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

Adding and taking away 21%
Increasing 58 by 21% gives 70.18 and decreasing it by 21% gives 45.82. These do not cancel out: raising 58 by 21% and then lowering the result by 21% ends at 55.4422, because the second 21% is taken of a bigger number.
