What Does Percentage Mean?
A percentage represents a number or ratio as a fraction out of 100. It utilizes the symbol “%” to denote it. In simple terms, it expresses any given number as a part of 100. For instance, 50% means 50 out of 100.
Percentages are widely used for comparisons. For example, if 75 out of 100 students passed an exam, it can be stated that 75% of the students were successful. This method of representation helps in easily comparing different quantities or values.
- Symbol: %
- Usage: Comparing values
- Example: 80% means 80 out of 100
What is the basic formula to find a student’s percentage of marks?
Percentage = (Obtained Marks/Total Marks) * 100
In this formula:
- Obtained Marks: The score received by the student.
- Total Marks: The maximum marks possible in the exam.
This calculation method is commonly applied in educational institutions to determine the percentage of marks a student has secured.
Examples of Calculating Percentage Marks
A student achieved 80 marks out of 100 in an exam. To determine the percentage, divide the obtained marks by the total marks and then multiply by 100.
- Obtained Marks: 80
- Total Marks: 100
- Percentage: (80/100) * 100 = 80%
In another instance, a student received 85 marks out of 100 on a physics test. Using the same formula, the percentage can be calculated.
- Obtained Marks: 85
- Total Marks: 100
- Percentage: (85/100) * 100 = 85%
For an English test, a student scored 38 out of 50 marks. The percentage calculation follows the same method:
- Obtained Marks: 38
- Total Marks: 50
- Percentage: (38/50) * 100 = 76%
Distinguishing Percentages and Fractions
Percentages and fractions are methods to represent portions of a whole. Percentages are expressed as fractions of 100 (e.g., 45% equals 45/100). Fractions show a ratio between two integers, like 3/4. Percentages are frequently used in finance and business, while fractions find more application in science and math.

How to Calculate the Percentage of Any Number
To determine the percentage of a number, use the formula:
Percentage = (Part/Whole) * 100
Here, Part is the number you want to find the percentage of, and Whole is the total value.
Example:
Given:
- Part: 33
- Whole: 200
Calculation:
Percentage = (33/200) * 100 = 16.5%
Thus, 33 is 16.5% of 200.
Useful tips and tricks for calculating percentages
- Calculating 50%: Simply divide the number by 2. For example, half of 30 is 15, as 30 divided by 2 equals 15.
- Percentages over 100%: Multiply the given number by the percentage and then divide by 100. For instance, 170% of 40 can be found by calculating (170/100) times 40, giving a result of 68.
- Getting 25%: Divide the value by 4 to find a quarter of it.
These straightforward methods can help in various scenarios, including computing grades, determining discounts, and assessing sales tax.
