1. What is Fraction Comparison?

Fraction comparison is the process of determining which of two fractions is larger, or if they are equal. This calculator provides two methods to compare fractions: converting to decimals or finding a common denominator.

2. How Does the Calculator Work?

The calculator uses either of these methods:

\[ \text{Decimal Method: } \frac{a}{b} \text{ vs } \frac{c}{d} \text{ becomes } a/b \text{ vs } c/d \] \[ \text{Common Denominator: } \frac{a \times (lcm/b)}{lcm} \text{ vs } \frac{c \times (lcm/d)}{lcm} \]

Where:

\( a, c \) — Numerators
\( b, d \) — Denominators
\( lcm \) — Least Common Multiple of denominators

3. Methods of Comparison

Decimal Conversion: Converts fractions to decimal form for direct numerical comparison.

Common Denominator: Finds equivalent fractions with the same denominator to compare numerators.

4. Using the Calculator

Tips: Enter numerators and denominators (must be positive integers). Select comparison method. The calculator will show which fraction is larger or if they're equal.

5. Frequently Asked Questions (FAQ)

Q1: Which method is more accurate?
A: Both methods are mathematically equivalent. Decimal conversion may be easier to understand visually.

Q2: What if denominators are the same?
A: The calculator will simply compare numerators directly.

Q3: Can I compare improper fractions?
A: Yes, the calculator works with both proper and improper fractions.

Q4: What's the maximum denominator size?
A: The calculator can handle very large numbers, but extremely large values may cause performance issues.

Q5: How are negative fractions handled?
A: Negative values are not currently supported in this calculator.
