How to work it out

  1. Turn the percentage into a decimal: 25 ÷ 100 = 0.25
  2. Multiply: 0.25 × 340 = 85
  3. Check: Work backwards: 85 ÷ 340 × 100 = 25%.

Another method. As a proportion of part to whole: 25/100 = part/340, so part = 25 × 340 ÷ 100 = 85. Both methods always give the same answer.

In a spreadsheet: =25%*340. 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 25% share of 340. The remaining 75% is 255, and the two parts add back up to 340.

Discounts: 25% off an item priced $340 saves $85, so you pay $255.

Adding and taking away 25%

Increasing 340 by 25% gives 425 and decreasing it by 25% gives 255. These do not cancel out: raising 340 by 25% and then lowering the result by 25% ends at 318.75, because the second 25% is taken of a bigger number.
