How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 49 = 44.1
  3. Check: Work backwards: 44.1 ÷ 49 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/49, so part = 90 × 49 ÷ 100 = 44.1. Both methods always give the same answer.

In a spreadsheet: =90%*49. 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

44.1 is the 90% share of 49. The remaining 10% is 4.9, and the two parts add back up to 49.

Discounts: 90% off an item priced $49 saves $44.1, so you pay $4.9.

Adding and taking away 90%

Increasing 49 by 90% gives 93.1 and decreasing it by 90% gives 4.9. These do not cancel out: raising 49 by 90% and then lowering the result by 90% ends at 9.31, because the second 90% is taken of a bigger number.
