How to work it out

  1. Turn the percentage into a decimal: 87 ÷ 100 = 0.87
  2. Multiply: 0.87 × 64 = 55.68
  3. Check: Work backwards: 55.68 ÷ 64 × 100 = 87%.

Another method. As a proportion of part to whole: 87/100 = part/64, so part = 87 × 64 ÷ 100 = 55.68. Both methods always give the same answer.

In a spreadsheet: =87%*64. 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

55.68 is the 87% share of 64. The remaining 13% is 8.32, and the two parts add back up to 64.

Discounts: 87% off an item priced $64 saves $55.68, so you pay $8.32.

Adding and taking away 87%

Increasing 64 by 87% gives 119.68 and decreasing it by 87% gives 8.32. These do not cancel out: raising 64 by 87% and then lowering the result by 87% ends at 15.5584, because the second 87% is taken of a bigger number.
