How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 58 = 52.2
  3. Check: Work backwards: 52.2 ÷ 58 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/58, so part = 90 × 58 ÷ 100 = 52.2. Both methods always give the same answer.

In a spreadsheet: =90%*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

52.2 is the 90% share of 58. The remaining 10% is 5.8, and the two parts add back up to 58.

Discounts: 90% off an item priced $58 saves $52.2, so you pay $5.8.

Adding and taking away 90%

Increasing 58 by 90% gives 110.2 and decreasing it by 90% gives 5.8. These do not cancel out: raising 58 by 90% and then lowering the result by 90% ends at 11.02, because the second 90% is taken of a bigger number.
