How to work it out

  1. Turn the percentage into a decimal: 61 ÷ 100 = 0.61
  2. Multiply: 0.61 × 30 = 18.3
  3. Check: Work backwards: 18.3 ÷ 30 × 100 = 61%.

Another method. As a proportion of part to whole: 61/100 = part/30, so part = 61 × 30 ÷ 100 = 18.3. Both methods always give the same answer.

In a spreadsheet: =61%*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

18.3 is the 61% share of 30. The remaining 39% is 11.7, and the two parts add back up to 30.

Discounts: 61% off an item priced $30 saves $18.3, so you pay $11.7.

Adding and taking away 61%

Increasing 30 by 61% gives 48.3 and decreasing it by 61% gives 11.7. These do not cancel out: raising 30 by 61% and then lowering the result by 61% ends at 18.837, because the second 61% is taken of a bigger number.
