How to work it out

  1. Turn the percentage into a decimal: 30 ÷ 100 = 0.3
  2. Multiply: 0.3 × 58 = 17.4
  3. Check: Work backwards: 17.4 ÷ 58 × 100 = 30%.

Another method. As a proportion of part to whole: 30/100 = part/58, so part = 30 × 58 ÷ 100 = 17.4. Both methods always give the same answer.

In a spreadsheet: =30%*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.

What the result means

17.4 is the 30% share of 58. The remaining 70% is 40.6, and the two parts add back up to 58.

Discounts: 30% off an item priced $58 saves $17.4, so you pay $40.6.

Adding and taking away 30%

Increasing 58 by 30% gives 75.4 and decreasing it by 30% gives 40.6. These do not cancel out: raising 58 by 30% and then lowering the result by 30% ends at 52.78, because the second 30% is taken of a bigger number.
