How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 49 = 10.29
  3. Check: Work backwards: 10.29 ÷ 49 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/49, so part = 21 × 49 ÷ 100 = 10.29. Both methods always give the same answer.

In a spreadsheet: =21%*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

10.29 is the 21% share of 49. The remaining 79% is 38.71, and the two parts add back up to 49.

Discounts: 21% off an item priced $49 saves $10.29, so you pay $38.71.

Adding and taking away 21%

Increasing 49 by 21% gives 59.29 and decreasing it by 21% gives 38.71. These do not cancel out: raising 49 by 21% and then lowering the result by 21% ends at 46.8391, because the second 21% is taken of a bigger number.
