How to work it out

  1. Turn the percentage into a decimal: 45 ÷ 100 = 0.45
  2. Multiply: 0.45 × 34 = 15.3
  3. Check: Work backwards: 15.3 ÷ 34 × 100 = 45%.

Another method. As a proportion of part to whole: 45/100 = part/34, so part = 45 × 34 ÷ 100 = 15.3. Both methods always give the same answer.

In a spreadsheet: =45%*34. 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

15.3 is the 45% share of 34. The remaining 55% is 18.7, and the two parts add back up to 34.

Discounts: 45% off an item priced $34 saves $15.3, so you pay $18.7.

Adding and taking away 45%

Increasing 34 by 45% gives 49.3 and decreasing it by 45% gives 18.7. These do not cancel out: raising 34 by 45% and then lowering the result by 45% ends at 27.115, because the second 45% is taken of a bigger number.
