How to work it out

  1. Turn the percentage into a decimal: 80 ÷ 100 = 0.8
  2. Multiply: 0.8 × 150 = 120
  3. Check: Work backwards: 120 ÷ 150 × 100 = 80%.

Another method. As a proportion of part to whole: 80/100 = part/150, so part = 80 × 150 ÷ 100 = 120. Both methods always give the same answer.

In a spreadsheet: =80%*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

120 is the 80% share of 150. The remaining 20% is 30, and the two parts add back up to 150.

Discounts: 80% off an item priced $150 saves $120, so you pay $30.

Adding and taking away 80%

Increasing 150 by 80% gives 270 and decreasing it by 80% gives 30. These do not cancel out: raising 150 by 80% and then lowering the result by 80% ends at 54, because the second 80% is taken of a bigger number.
