### Understanding Percentages

What Are Percentages?

Percentages are a way to express a fraction of a whole as a fraction of 100. They are denoted by the symbol "%." For example, 50% represents half of a whole, while 25% represents one-quarter.

### Basic Percentage Calculations

How to Calculate Percentages?

Percentage of a Number:
To calculate a percentage of a number, multiply the number by the percentage (in decimal form). For example, to find 20% of 80, you would multiply 80 by 0.20 (20% as a decimal).

Percentage Increase:
To calculate a percentage increase, subtract the original value from the new value, divide by the original value, and multiply by 100. For example, if a product's price increased from $50 to $60, the percentage increase is [(60 - 50) / 50] * 100 = 20%.

Percentage Decrease:
To calculate a percentage decrease, use the same formula as for percentage increase but subtract the new value from the original value. For example, if a discount reduces a $120 item to $96, the percentage decrease is [(120 - 96) / 120] * 100 = 20%.

Percentage of Total Marks:
To calculate your percentage based on total marks, divide your obtained marks by the total marks and multiply by 100. For example, if you scored 85 out of 100, your percentage is (85 / 100) * 100 = 85%.

Percentage to Decimal and GPA:
To convert a percentage to a decimal for GPA calculations, divide the percentage by 100. For example, a percentage of 75% becomes 0.75 for GPA calculations.

CGPA to Percentage:
To convert Cumulative Grade Point Average (CGPA) to a percentage, use your institution's conversion formula. It typically involves multiplying the CGPA by a constant value.
