Talking in a mathematical way, you can understand percentage as a number or a ratio that is expressed as a fraction of 100. The percentage is denoted by a % sign and is used as a deciding criteria for the grades of students at global level. Not just percentage of children, but to calculate annual interest, compound interest and commission purposes, you may need to work out percentage to judge what part you are getting from the entire portion and thus in this article we have come with some tips for you to work it out in certain ways.

1. Simple calculation of Percentage:-

Suppose there are 100 matchsticks in a matchbox, I order you to take 40 out of them, then the total number of matchsticks will be regarded as the hundred percent of the calculation and the 40 match sticks that you picked up will be the percentage that you got from the entire percentage. Now if I ask you the percentage of match sticks that you are having, you will simply answer that you have got 40% of the match sticks.

2. Getting Somewhat Tough:-

The approach that we followed in the step one was as simple as we teach a nursery going kid, but it was necessary to clear your basics. Now getting somewhat tough, If I ask you to calculate the percentage of some number greater than 100 like calculate the percentage of marks that you got from total of 250 if your score is 150?

It is as simple as the step one now as well. Simple divide 250 by 100, It will come to be 2.5 and thus one percent = 2.5 marks and now in order to calculate the percentage that you secured, simply divide 150 by 2.5 and you will get your percentage i.e. 60%

3. Calculation of The Overall Aggregate:-

It is but obvious that if you are to work out percentage in bulk like to find the aggregate marks of a student in all the subjects, you will need to follow a separate approach. Simply calculate the grand total of all the marks that a child secured in the respective subjects and all the grand total of maximum marks limit in that subject.

Suppose maximum marks limit in every subject is 100 marks and a student secures 50, 60, 70, 80, & 90 marks respectively in five of his subjects. In order to take the aggregate percentage, we will first of all add the maximum marks limit in every subject, i.e. 100+ 100+ 100 + 100 + 100 = 500 and then we will calculate the total which he secured i.e. 50 + 60 + 70 + 80 + 90 = 350

In order to calculate the aggregate percentage, you simply need to put 500 = 100 i.e. five marks = one percent and thus dividing 350 with 5, we get 70 % which is the aggregate percentage that the student has secured. Howsoever the tough a calculation may be, you just need to follow the same concept each time. Put the maximum grand total = 100, find out how many units = 1 % and divide the number that you get with the number that you get after doing so. As simple as that.
