How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 47 = 42.3
  3. Check: Work backwards: 42.3 ÷ 47 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/47, so part = 90 × 47 ÷ 100 = 42.3. Both methods always give the same answer.

In a spreadsheet: =90%*47. 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

42.3 is the 90% share of 47. The remaining 10% is 4.7, and the two parts add back up to 47.

Discounts: 90% off an item priced $47 saves $42.3, so you pay $4.7.

Adding and taking away 90%

Increasing 47 by 90% gives 89.3 and decreasing it by 90% gives 4.7. These do not cancel out: raising 47 by 90% and then lowering the result by 90% ends at 8.93, because the second 90% is taken of a bigger number.
