1. What Are Fractions?

A fraction represents a part of a whole or, more generally, any number of equal parts. It consists of a numerator (top number) and a denominator (bottom number) separated by a fraction bar.

2. How To Calculate Fractions

The basic fraction calculation formula is:

Where:

• \( a \) — Numerator (the number above the fraction line)
• \( b \) — Denominator (the number below the fraction line)
• \( \div \) — Division operator

Explanation: To calculate a fraction, simply divide the numerator by the denominator using a calculator.

3. Calculator Usage

Details: Enter the numerator and denominator values in the calculator above. The denominator cannot be zero (division by zero is undefined).

4. Practical Examples

Examples:

• 1/2 = 1 ÷ 2 = 0.5
• 3/4 = 3 ÷ 4 = 0.75
• 2/1 = 2 ÷ 1 = 2

5. Frequently Asked Questions (FAQ)

Q1: Can the denominator be zero?
A: No, division by zero is mathematically undefined.

Q2: How do I simplify fractions?
A: Find the greatest common divisor (GCD) of numerator and denominator, then divide both by it.

Q3: What's the difference between proper and improper fractions?
A: Proper fractions have numerator less than denominator (e.g., 1/2), improper have numerator greater than or equal to denominator (e.g., 5/2).

Q4: How to convert decimal to fraction?
A: Multiply decimal by power of 10 to eliminate decimal places, then simplify (e.g., 0.75 = 75/100 = 3/4).

Q5: Can I calculate mixed numbers?
A: Yes, first convert to improper fraction (e.g., 1½ = 3/2), then calculate.
