How to work it out

  1. Turn the percentage into a decimal: 54 ÷ 100 = 0.54
  2. Multiply: 0.54 × 90 = 48.6
  3. Check: Work backwards: 48.6 ÷ 90 × 100 = 54%.

Another method. As a proportion of part to whole: 54/100 = part/90, so part = 54 × 90 ÷ 100 = 48.6. Both methods always give the same answer.

In a spreadsheet: =54%*90. 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

48.6 is the 54% share of 90. The remaining 46% is 41.4, and the two parts add back up to 90.

Discounts: 54% off an item priced $90 saves $48.6, so you pay $41.4.

Adding and taking away 54%

Increasing 90 by 54% gives 138.6 and decreasing it by 54% gives 41.4. These do not cancel out: raising 90 by 54% and then lowering the result by 54% ends at 63.756, because the second 54% is taken of a bigger number.
