How to work it out

  1. Turn the percentage into a decimal: 70 ÷ 100 = 0.7
  2. Multiply: 0.7 × 91 = 63.7
  3. Check: Work backwards: 63.7 ÷ 91 × 100 = 70%.

Another method. As a proportion of part to whole: 70/100 = part/91, so part = 70 × 91 ÷ 100 = 63.7. Both methods always give the same answer.

In a spreadsheet: =70%*91. 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

63.7 is the 70% share of 91. The remaining 30% is 27.3, and the two parts add back up to 91.

Discounts: 70% off an item priced $91 saves $63.7, so you pay $27.3.

Adding and taking away 70%

Increasing 91 by 70% gives 154.7 and decreasing it by 70% gives 27.3. These do not cancel out: raising 91 by 70% and then lowering the result by 70% ends at 46.41, because the second 70% is taken of a bigger number.
