| AllCalc: How do I calculate percentages? |
In order to calculate some percent of a number you will have to enter the percentage as a decimal value. This is fairly easy since a percentage is just another way to express a number of 1/100ths.
10% = 0.10
20% = 0.20
42% = 0.42
63.47% = 0.6347
For example to calculate 25% of 4 execute the calculation 0.25 x 4
To determine the percentage that one number is relative to another, divide the partial number by the whole number and multiply the result by 100.
For example, if there are 50 emails and 10 of them have been read then the percentage of read emails is calculated as 10 / 50 = 0.20 which (x 100) is 20%.
