How to work it out

  1. Turn the percentage into a decimal: 40 ÷ 100 = 0.4
  2. Multiply: 0.4 × 89 = 35.6
  3. Check: Work backwards: 35.6 ÷ 89 × 100 = 40%.

Another method. As a proportion of part to whole: 40/100 = part/89, so part = 40 × 89 ÷ 100 = 35.6. Both methods always give the same answer.

In a spreadsheet: =40%*89. 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

35.6 is the 40% share of 89. The remaining 60% is 53.4, and the two parts add back up to 89.

Discounts: 40% off an item priced $89 saves $35.6, so you pay $53.4.

Adding and taking away 40%

Increasing 89 by 40% gives 124.6 and decreasing it by 40% gives 53.4. These do not cancel out: raising 89 by 40% and then lowering the result by 40% ends at 74.76, because the second 40% is taken of a bigger number.
