1. What is Fraction Simplification?

Fraction simplification is the process of reducing a fraction to its simplest form where the numerator and denominator have no common divisors other than 1. This is done by dividing both the numerator and denominator by their greatest common divisor (GCD).

2. How Does the Calculator Work?

The calculator uses the following mathematical principle:

Where:

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

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

3. Importance of Simplified Fractions

Details: Simplified fractions are easier to work with in calculations and comparisons. They represent the same value in the most reduced form, making mathematical expressions cleaner and more understandable.

4. Using the Calculator

Tips: Enter positive integers for both numerator and denominator. The calculator will find the GCD and display both the GCD and the simplified fraction.

5. Frequently Asked Questions (FAQ)

Q1: What if I enter a numerator larger than the denominator?
A: The calculator works the same way - it will simplify improper fractions just as it does proper fractions.

Q2: How is the GCD calculated?
A: Using the Euclidean algorithm, which efficiently finds the greatest common divisor through a series of division steps.

Q3: What about negative numbers?
A: This calculator only accepts positive integers. For negative fractions, you would simplify the absolute values first, then apply the negative sign to either the numerator or denominator.

Q4: Can this handle very large numbers?
A: Yes, within the limits of PHP's integer handling. The Euclidean algorithm is efficient even for large numbers.

Q5: What if the fraction is already in simplest form?
A: The calculator will return the GCD as 1 and the same fraction you entered, confirming it's already simplified.
