How to work it out

  1. Turn the percentage into a decimal: 24 ÷ 100 = 0.24
  2. Multiply: 0.24 × 30 = 7.2
  3. Check: Work backwards: 7.2 ÷ 30 × 100 = 24%.

Another method. As a proportion of part to whole: 24/100 = part/30, so part = 24 × 30 ÷ 100 = 7.2. Both methods always give the same answer.

In a spreadsheet: =24%*30. 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

7.2 is the 24% share of 30. The remaining 76% is 22.8, and the two parts add back up to 30.

Discounts: 24% off an item priced $30 saves $7.2, so you pay $22.8.

Adding and taking away 24%

Increasing 30 by 24% gives 37.2 and decreasing it by 24% gives 22.8. These do not cancel out: raising 30 by 24% and then lowering the result by 24% ends at 28.272, because the second 24% is taken of a bigger number.
