Percentage helps us understand the fraction of any number in accordance with the complete or total value. For example at school when you got to compare the marks or calculate the highest marks among the students you tend to obtain a percentage from the marks obtained in the exam.
You can calculate the total percentage of any particular number by dividing the number by the total to which it is been compared and then multiplying the result by 100.
e.g: A student got 100 marks out of 500. So the percentage calculated would be as given below:
(100/500) X 100 = 20%
