How to Get a Percentage in Standard American English
A percentage is a fraction or ratio expressed as a hundredth. It is often used to represent a part of a whole, such as the percentage of students who passed a test or the percentage of voters who support a particular candidate.
To get a percentage, you divide the part by the whole and then multiply by 100. For example, if 80 students out of 100 pass a test, the percentage of students who passed is 80/100 * 100 = 80%.
Steps to Get a Percentage
- Identify the part and the whole. The part is the number or amount that you are interested in, and the whole is the total number or amount.
- Divide the part by the whole. This will give you a decimal number.
- Multiply the decimal number by 100. This will convert the decimal number to a percentage.
Example
Let’s say you want to find the percentage of people who voted for a particular candidate in an election. You know that the candidate received 500 votes out of a total of 1000 votes cast.
To find the percentage, you would divide 500 by 1000 and then multiply by 100:
500 / 1000 * 100 = 50%
Therefore, the candidate received 50% of the votes cast.
