Before we dive into the conversion, let’s clarify what a fraction represents. A fraction, like 7/2, signifies a part of a whole:

• 7 is the numerator (the amount you have).
• 2 is the denominator (the total parts that make up a whole).

Key Concept:

🔢 A fraction shows the division of the numerator by the denominator.

Converting Fractions to Decimals

Steps to Conversion:

1. Divide the numerator by the denominator:
   [ 7 ÷ 2 = 3.5 ]

2. Write down the result:
   Now we have 3.5 as our decimal.

<p class="pro-note">💡 Note: When dividing, remember that any remainder or non-repeating decimal will require rounding for the sake of percentage conversion.</p>

From Decimals to Percentages

Once you have the decimal, converting to a percentage is straightforward:

1. Multiply the decimal by 100:
   [ 3.5 × 100 = 350 ]

2. Add the percent symbol (%):
   Hence, 7/2 as a percentage is 350%.

Common Misconception:

🧠 Don’t multiply the numerator or the denominator by 100 directly without turning it into a decimal first.

Practical Applications
