How To Calculate Percentage? To calculate the percentage of a number out of the total number, just use the formula = number / total number × 100
To calculate a percentage, follow these steps:
Determine the part and the whole: You need to know what portion of a whole you are interested in. For example, if you want to calculate the percentage of students who passed a exam, you need to know how many students passed and how many students took the exams.
Divide the part by the whole: To find the decimal form of the percentage, divide the part (e.g. number of students who passed) by the whole (e.g. number of students who took the test).
Multiply the decimal by 100: To convert the decimal to a percentage, multiply it by 100. This will give you the percentage of the part in relation to the whole.
For example, let's say 80 students passed a test out of 100 students who took it. To calculate the percentage of students who passed, you would divide 80 by 100, which gives you 0.8. To convert this decimal to a percentage, multiply it by 100, which gives you 80%. Therefore, the percentage of students who passed the test is 80%.
Another example: if you want to find what is 15% of 100, you can multiply 0.15 (which is the decimal form of 15%) by 100, which gives you 15.
So, the general formula to calculate a percentage is:
Percentage = (Part / Whole) x 100
