How to work it out

  1. Turn the percentage into a decimal: 42 ÷ 100 = 0.42
  2. Multiply: 0.42 × 86 = 36.12
  3. Check: Work backwards: 36.12 ÷ 86 × 100 = 42%.

Another method. As a proportion of part to whole: 42/100 = part/86, so part = 42 × 86 ÷ 100 = 36.12. Both methods always give the same answer.

In a spreadsheet: =42%*86. 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

36.12 is the 42% share of 86. The remaining 58% is 49.88, and the two parts add back up to 86.

Discounts: 42% off an item priced $86 saves $36.12, so you pay $49.88.

Adding and taking away 42%

Increasing 86 by 42% gives 122.12 and decreasing it by 42% gives 49.88. These do not cancel out: raising 86 by 42% and then lowering the result by 42% ends at 70.8296, because the second 42% is taken of a bigger number.
