How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 150 = 15
  3. Check: Work backwards: 15 ÷ 150 × 100 = 10%.

Another method. As a proportion of part to whole: 10/100 = part/150, so part = 10 × 150 ÷ 100 = 15. Both methods always give the same answer.

In a spreadsheet: =10%*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

15 is the 10% share of 150. The remaining 90% is 135, and the two parts add back up to 150.

Discounts: 10% off an item priced $150 saves $15, so you pay $135.

Adding and taking away 10%

Increasing 150 by 10% gives 165 and decreasing it by 10% gives 135. These do not cancel out: raising 150 by 10% and then lowering the result by 10% ends at 148.5, because the second 10% is taken of a bigger number.
