How to Calculate Percentage of Marks?

Compute your percentage of marks effortlessly with a straightforward two-step process:

Step 1: Divide your earned marks by the maximum marks attainable in the test.

Step 2: Multiply the outcome by 100.

This simple formula simplifies the calculation, making it a quick and effective way to determine your percentage score.

Example 1: Calculate the percentage of marks for 6 subjects. English 78, History 90, Geography 85, Economics 79, Political Science 88, and Sociology 75.

Solution:

Total marks scored – 78 + 90 + 85 + 79 + 88 + 75 = 495

Maximum marks = 600

Percentage of marks – (495/600) x 100 = 82.5%

Difference between Percentage and Percentile: How to Calculate Percentage of Marks?

People often get confused between percentages and percentile. The percentage can be defined as a portion of a whole and is used to express a relative part of 100. It is commonly used for grading, scoring or expressing proportions. Meanwhile, the percentile can be defined as the rank of a particular score in the group. 

For example, many standardised tests like the SAT or GRE report scores in percentile, indicating how the candidate has performed depending on a candidate’s performance relative to other candidates. At the same time, the percentage might represent the number of correct answers out of the total questions but will not provide a comparison with a broader population. 

The detailed differences between percentage and percentile are given below:

Percentage	Percentile
It can be expressed as a number out of 100	It is not expressed as an integer between 0 and 100
It can be indicated as a ratio or proportion	It cannot be indicated as a ratio or proportion
It can be obtained by multiplying the ratio of two values by 100.	It can be obtained by the percentage of values found below a certain value.

How to Convert Fractions to Percentages?

Percentage is like expressing a number out of 100, while a fraction represents a part of a whole, such as 1 out of 4. 

In a percentage, 100 is the whole amount, and you describe a portion of it, but in a fraction, the bottom number (denominator) is the entire amount you’re talking about. 

It’s like using different ways to talk about parts of a whole, where 100 is the full thing in percentages, and the denominator is the full thing in fractions.

How to Calculate Percentage of Marks/Numbers?

You can calculate percentages for a number by two approaches. The first method is called the fraction form. If you get a number in fraction form, convert it to decimal and multiply the result by 100. 

For Example: If the fraction number is 30/50, the result will be 0.6, and if you multiply by 100, it will be 60%.

The second approach is the decimal method. If you have a number using the decimal method, you can directly convert it into a percentage by multiplying it by 100. 

For Example: If the decimal number is 0.75436, the result will be 0.754 x 100= 75.4%.

Calculate Percentage Increase

Percentage increase is the increase in the final value with respect to the original value, expressed as a percentage. The change can be calculated using the following formula:

Percentage Increase (%) = Increase in Quantity x 100/ Initial value. 

In this case, Increase Quantity = Final value- Initial Value

Calculate Percentage Decrease

Percentage decrease is the decrease in the final value with respect to the original value, expressed as a percentage. The change can be calculated using the following formula:

Percentage Decrease (%) = Decrease in Quantity x 100/ Initial value.

In this case, Decrease Quantity = Final value- Initial Value.

Questions to Calculate Percentage of Marks 

1. Calculate the total percentage if a student scores 55, 60, 75, 68, and 72 in 5 subjects out of 80.
2. Mary scored 85 marks in her first exam out of 120. If she aims for a 90% overall score, how many marks does she need in the next exam?
3. Rahul got 480 marks out of 600 in a school test. Calculate the percentage of marks he scored.
4. A student scored 93, 87, and 95 in three subjects out of 100. Calculate the average percentage.

Tips and Tricks to Solve the Problems of How to Calculate Percentage of Marks

• If you want to search for 50 per cent of a number, you can divide the number by two. For example, 50% of 30 is 30/2 = 15.
