1. What is Fraction Reduction?

Fraction reduction is the process of simplifying a fraction to its lowest terms by dividing both the numerator and denominator by their greatest common divisor (GCD). This results in an equivalent fraction that is simpler and easier to work with.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( a \) — Numerator (unitless)
• \( b \) — Denominator (unitless)
• \( g \) — Greatest common divisor of a and b (unitless)

Explanation: The calculator finds the GCD of the numerator and denominator, then divides both by this value to produce the reduced fraction.

3. Importance of Reducing Fractions

Details: Reduced fractions are easier to understand, compare, and work with in mathematical operations. They represent the simplest form of the original fraction.

4. Using the Calculator

Tips: Enter positive integers for both numerator and denominator. The calculator will find the GCD and reduce the fraction to its simplest form.

5. Frequently Asked Questions (FAQ)

Q1: What if my fraction is already in simplest form?
A: The calculator will return the same fraction with a GCD of 1.

Q2: Can I use this for mixed numbers?
A: First convert mixed numbers to improper fractions, then use the calculator.

Q3: What's the largest number this calculator can handle?
A: It depends on your server's PHP configuration, but typically handles very large numbers well.

Q4: How is the GCD calculated?
A: Using the Euclidean algorithm, which efficiently finds the GCD through repeated division.

Q5: Can this calculator handle negative numbers?
A: No, it's designed for positive integers only. For negative fractions, use absolute values then apply the sign to the reduced fraction.
