How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 23 = 20.01
  3. Check: Work backwards: 20.01 ÷ 23 × 100 = 87%.

Another method. As a proportion of part to whole: 87/100 = part/23, so part = 87 × 23 ÷ 100 = 20.01. Both methods always give the same answer.

In a spreadsheet: =87%*23. 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

20.01 is the 87% share of 23. The remaining 13% is 2.99, and the two parts add back up to 23.

Discounts: 87% off an item priced $23 saves $20.01, so you pay $2.99.

Adding and taking away 87%

Increasing 23 by 87% gives 43.01 and decreasing it by 87% gives 2.99. These do not cancel out: raising 23 by 87% and then lowering the result by 87% ends at 5.5913, because the second 87% is taken of a bigger number.
