How to work it out

  1. Turn the percentage into a decimal: 21 ÷ 100 = 0.21
  2. Multiply: 0.21 × 98 = 20.58
  3. Check: Work backwards: 20.58 ÷ 98 × 100 = 21%.

Another method. As a proportion of part to whole: 21/100 = part/98, so part = 21 × 98 ÷ 100 = 20.58. Both methods always give the same answer.

In a spreadsheet: =21%*98. 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

20.58 is the 21% share of 98. The remaining 79% is 77.42, and the two parts add back up to 98.

Discounts: 21% off an item priced $98 saves $20.58, so you pay $77.42.

Adding and taking away 21%

Increasing 98 by 21% gives 118.58 and decreasing it by 21% gives 77.42. These do not cancel out: raising 98 by 21% and then lowering the result by 21% ends at 93.6782, because the second 21% is taken of a bigger number.
