How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 150 = 135
  3. Check: Work backwards: 135 ÷ 150 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/150, so part = 90 × 150 ÷ 100 = 135. Both methods always give the same answer.

In a spreadsheet: =90%*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

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

Discounts: 90% off an item priced $150 saves $135, so you pay $15.

Adding and taking away 90%

Increasing 150 by 90% gives 285 and decreasing it by 90% gives 15. These do not cancel out: raising 150 by 90% and then lowering the result by 90% ends at 28.5, because the second 90% is taken of a bigger number.
