Percentage = (Value ÷ Total) × 100

Example:

If the value is 40 and the total is 200:

Percentage = (40 ÷ 200) × 100
Percentage = 20%

This means 40 is 20% of 200.

Suppose a student scores 72 marks out of 90.

• Value = 72
• Total = 90

Result:

• Percentage Rate = 80%
• Difference = 18
• Remaining Percentage = 20%

This means the student achieved 80% marks.

Example 2: Shopping Discount

A product originally costs $500, and the discount amount is $125.

• Value = 125
• Total = 500

Result:

• Percentage Rate = 25%
• Difference = 375
• Remaining Percentage = 75%

The product has a 25% discount.

Example 3: Business Profit Analysis

A company earns $15,000 profit from total sales of $60,000.

• Value = 15000
• Total = 60000

Result:

• Percentage Rate = 25%
