How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 53 = 47.7
  3. Check: Work backwards: 47.7 ÷ 53 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/53, so part = 90 × 53 ÷ 100 = 47.7. Both methods always give the same answer.

In a spreadsheet: =90%*53. 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

47.7 is the 90% share of 53. The remaining 10% is 5.3, and the two parts add back up to 53.

Discounts: 90% off an item priced $53 saves $47.7, so you pay $5.3.

Adding and taking away 90%

Increasing 53 by 90% gives 100.7 and decreasing it by 90% gives 5.3. These do not cancel out: raising 53 by 90% and then lowering the result by 90% ends at 10.07, because the second 90% is taken of a bigger number.
