How to work it out

  1. Turn the percentage into a decimal: 50 ÷ 100 = 0.5
  2. Multiply: 0.5 × 170 = 85
  3. Check: Work backwards: 85 ÷ 170 × 100 = 50%.

Another method. As a proportion of part to whole: 50/100 = part/170, so part = 50 × 170 ÷ 100 = 85. Both methods always give the same answer.

In a spreadsheet: =50%*170. 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

85 is the 50% share of 170. The remaining 50% is 85, and the two parts add back up to 170.

Discounts: 50% off an item priced $170 saves $85, so you pay $85.

Adding and taking away 50%

Increasing 170 by 50% gives 255 and decreasing it by 50% gives 85. These do not cancel out: raising 170 by 50% and then lowering the result by 50% ends at 127.5, because the second 50% is taken of a bigger number.
