How to Calculate Percentage

Step 1: Identify the "Part" and the "Whole"

First, determine the part and the whole values. The part is the value you want to find the percentage of, and the whole is the total or complete value.

Example: If you scored 45 marks out of 50 in an exam, then:

Part = 45, Whole = 50

Step 2: Divide the Part by the Whole

Next, divide the part by the whole to get the fraction:

45 ÷ 50 = 0.9

Step 3: Multiply by 100

Now, multiply the result by 100 to convert the fraction into a percentage:

0.9 × 100 = 90%

Step 4: Final Answer

Your final result is the percentage:

90% is the percentage you scored.

Example: Calculating Discount

If you bought a shirt for ₹600 with a 20% discount, follow these steps:

Step 1: Identify the part and whole. 
Part = 20%, Whole = ₹600

Step 2: Calculate the percentage of ₹600.

20 ÷ 100 × 600 = ₹120

Result: The discount is ₹120.
