To find the percentage of a number, you can use the following formula:
(part / whole) x 100 = percentage
For example, if you want to find out what percentage 15 is of 50:
(15 / 50) x 100 = 30%
Another example, if you want to find out what percent 20 is of 100:
(20 / 100) x 100 = 20%
So, in general, you divide the part (the number you want to find the percentage of) by the whole (the total number in the set or problem), and then multiply the result by 100 to express it as a percentage.
You can also use a calculator or excel spreadsheet to find percentage, some of them even have specific function for that.
