If you’re a student or a teacher, you’ve probably needed to calculate percentage for marks at some point. Whether you’re trying to figure out your grade for a class or grading assignments, knowing how to calculate percentage is essential. In this article, we’ll take a look at the ins and outs of how to calculate percentage for marks.
Calculating percentages can be a pain point for many people. If you’re not good at math or if it’s been a long time since you learned how to calculate percentages, it can feel overwhelming. Additionally, calculating percentages can be time-consuming, especially if you’re dealing with a lot of numbers. It’s important to understand the basics of how to calculate percentage so that you can do it quickly and accurately.
The formula for calculating percentage is simple: divide the part by the whole and multiply by 100. For example, if you got 70 out of 100 on an exam, you would divide 70 by 100 and then multiply by 100 to get 70%. This formula can be used to calculate the percentage of any number or set of numbers.
To summarize, calculating percentage involves dividing the part by the whole and multiplying by 100. This formula can be applied to any number or set of numbers. Additionally, practice is the key to mastering how to calculate percentage.
Why is it important to know how to calculate percentage?
Knowing how to calculate percentage is essential for a variety of reasons. For students, calculating grades and understanding how they are calculated is critical to academic success. Additionally, teachers need to calculate grades for their students accurately. For anyone working with numbers in their job, understanding percentages is necessary. Even in everyday life, knowing how to calculate a percentage can come in handy when shopping, budgeting, or making other financial decisions.
How to calculate percentage of marks – step by step
Calculating percentages can be a straightforward process. Here is a step-by-step guide to help you calculate percentage:
- Determine the percentage you want to find.
- Determine the total value of the data set.
- Determine the value of the part of the data set that you want to find the percentage of.
- Divide the value of the part by the total value.
- Multiply by 100 to get the percentage.
For example, if you want to find the percentage of marks you got in a test, you would follow these steps:
- Determine the percentage you want to find (let’s say 70%).
- Determine the total value of the data set (let’s say it was 100 marks).
- Determine the value of the part of the data set that you want to find the percentage of (let’s say you got 70 marks).
- Divide the value of the part by the total value (70 / 100 = 0.7).
- Multiply by 100 to get the percentage (0.7 x 100 = 70%).
Using examples to calculate percentage
Let’s take a look at a few more examples of how to calculate percentage:
Example 1:
You got 17 out of 20 in a quiz. What is your percentage score?
- The percentage you want to find is 100%
- The total value of the data set is 20.
- The value of the part of the data set that you want to find the percentage of is 17.
- Dividing the value of the part by the total value gives you 0.85.
- Multiplying by 100 gives you a percentage of 85%.
So, your percentage score in the quiz is 85%.
Example 2:
Your class has completed ten tests, and you got an average of 8.5 marks out of 10 on each test. What is your overall percentage score?
- The percentage you want to find is 100%
- The total value of the data set is 100 (10 tests x 10 marks per test).
- The value of the part of the data set that you want to find the percentage of is 85 (10 tests x 8.5 marks per test).
- Dividing the value of the part by the total value gives you 0.85.
- Multiplying by 100 gives you a percentage of 85%.
So, your overall percentage score for the ten tests is 85%.
Using a percentage calculator
If you don’t want to do the math yourself, you can use a percentage calculator to do it for you. There are many percentage calculators available online for free, and they can save you time and effort in calculating percentages.
Tips for calculating percentage of marks
Here are some tips to help you calculate percentages more easily:
- Always double-check your calculations.

- Practice, practice, practice! The more you practice, the easier calculating percentage will become.
Question and Answer
Q: What are some common mistakes to avoid when calculating percentage?
A: Some common mistakes to avoid include forgetting to multiply by 100, not dividing the part by the whole, and rounding incorrectly. Additionally, always make sure to double-check your calculations.
Q: Can percentages be negative?
A: No, percentages cannot be negative. They represent a fraction of a whole, so they cannot be less than zero.
Q: How do I calculate a percentage increase or decrease?
A: To calculate a percentage increase, subtract the old value from the new value, divide the result by the old value, and multiply by 100. To calculate a percentage decrease, do the same thing but subtract the new value from the old value instead.
Q: Can percentages be greater than 100%?
A: Yes, percentages can be greater than 100%. This usually happens when measuring changes or growth rates.
Conclusion of how to calculate percentage for marks
Knowing how to calculate percentage for marks is essential for students, teachers, and anyone working with numbers.
