How to work it out

  1. Turn the percentage into a decimal: 30 ÷ 100 = 0.3
  2. Multiply: 0.3 × 150 = 45
  3. Check: Work backwards: 45 ÷ 150 × 100 = 30%.

Another method. As a proportion of part to whole: 30/100 = part/150, so part = 30 × 150 ÷ 100 = 45. Both methods always give the same answer.

In a spreadsheet: =30%*150. 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

45 is the 30% share of 150. The remaining 70% is 105, and the two parts add back up to 150.

Discounts: 30% off an item priced $150 saves $45, so you pay $105.

Adding and taking away 30%

Increasing 150 by 30% gives 195 and decreasing it by 30% gives 105. These do not cancel out: raising 150 by 30% and then lowering the result by 30% ends at 136.5, because the second 30% is taken of a bigger number.
