How to Get Percentage in Standard American English
Percentage is a mathematical term used to represent a part of a whole as a fraction of 100. It is often used to express the proportion of something in relation to the whole. For example, if you have 50 apples out of a total of 100 apples, you would say that you have 50% of the apples.
There are several ways to get a percentage in Standard American English. The most common method is to use the following formula:
Percentage = (Part / Whole) x 100Here, ‘Part’ refers to the part of the whole that you are interested in, and ‘Whole’ refers to the total amount.
Example:
Suppose you have a class of 30 students, and 15 of them are girls. To find the percentage of girls in the class, you would use the following formula:
Percentage of girls = (15 / 30) x 100This calculation would give you the answer: 50%. Therefore, 50% of the students in the class are girls.
Another method to get a percentage is to use the following steps:
- Convert the whole number to a decimal.
- Divide the part by the converted whole number.
- Multiply the result by 100.
Example:
Using the same example as above, we can calculate the percentage of girls in the class using this method:
- Convert the whole number (30) to a decimal: 30 = 30.0
- Divide the part (15) by the converted whole number: 15 / 30.0 = 0.5
- Multiply the result by 100: 0.5 x 100 = 50%
Both methods will give you the same result: 50%.
Here are some additional tips for getting a percentage in Standard American English:
- Always make sure to round your answer to the nearest whole number.
- If the percentage is less than 1%, write it as a decimal. For example, 0.5% instead of 0.5%.
- When writing a percentage, use the percent sign (%) after the number. For example, 50% instead of 50 percent.
