How to work it out

  1. Turn the percentage into a decimal: 34 ÷ 100 = 0.34
  2. Multiply: 0.34 × 87 = 29.58
  3. Check: Work backwards: 29.58 ÷ 87 × 100 = 34%.

Another method. As a proportion of part to whole: 34/100 = part/87, so part = 34 × 87 ÷ 100 = 29.58. Both methods always give the same answer.

In a spreadsheet: =34%*87. 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

29.58 is the 34% share of 87. The remaining 66% is 57.42, and the two parts add back up to 87.

Discounts: 34% off an item priced $87 saves $29.58, so you pay $57.42.

Adding and taking away 34%

Increasing 87 by 34% gives 116.58 and decreasing it by 34% gives 57.42. These do not cancel out: raising 87 by 34% and then lowering the result by 34% ends at 76.9428, because the second 34% is taken of a bigger number.
