How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 85 = 76.5
  3. Check: Work backwards: 76.5 ÷ 85 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/85, so part = 90 × 85 ÷ 100 = 76.5. Both methods always give the same answer.

In a spreadsheet: =90%*85. 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

76.5 is the 90% share of 85. The remaining 10% is 8.5, and the two parts add back up to 85.

Discounts: 90% off an item priced $85 saves $76.5, so you pay $8.5.

Adding and taking away 90%

Increasing 85 by 90% gives 161.5 and decreasing it by 90% gives 8.5. These do not cancel out: raising 85 by 90% and then lowering the result by 90% ends at 16.15, because the second 90% is taken of a bigger number.
