How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 7 = 6.3
  3. Check: Work backwards: 6.3 ÷ 7 × 100 = 90%.

Another method. As a proportion of part to whole: 90/100 = part/7, so part = 90 × 7 ÷ 100 = 6.3. Both methods always give the same answer.

In a spreadsheet: =90%*7. 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

6.3 is the 90% share of 7. The remaining 10% is 0.7, and the two parts add back up to 7.

Discounts: 90% off an item priced $7 saves $6.3, so you pay $0.7.

Adding and taking away 90%

Increasing 7 by 90% gives 13.3 and decreasing it by 90% gives 0.7. These do not cancel out: raising 7 by 90% and then lowering the result by 90% ends at 1.33, because the second 90% is taken of a bigger number.
