90% as decimal
0.9
4 + 90%
7.6

How to work it out

  1. Turn the percentage into a decimal: 90 ÷ 100 = 0.9
  2. Multiply: 0.9 × 4 = 3.6
  3. Check: Work backwards: 3.6 ÷ 4 × 100 = 90%.

In a spreadsheet: =90%*4. 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

3.6 is the 90% share of 4. The remaining 10% is 0.4, and the two parts add back up to 4.

Discounts: 90% off an item priced $4 saves $3.6, so you pay $0.4.

Adding and taking away 90%

Increasing 4 by 90% gives 7.6 and decreasing it by 90% gives 0.4. These do not cancel out: raising 4 by 90% and then lowering the result by 90% ends at 0.76, because the second 90% is taken of a bigger number.
