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 uses the cross-multiplication method to compare fractions accurately without converting them to decimals.

2. How Does the Calculator Work?

The calculator uses the cross-product method:

Where:

• \( \frac{a}{b} \) — First fraction to compare
• \( \frac{c}{d} \) — Second fraction to compare

Explanation: By cross-multiplying the numerators and denominators, we can compare the fractions without finding a common denominator.

3. Importance of Fraction Comparison

Details: Comparing fractions is fundamental in mathematics, useful in everyday situations like comparing measurements, ratios, or probabilities.

4. Using the Calculator

Tips: Enter the numerators and denominators of both fractions. Denominators must be positive numbers. The calculator will show which fraction is larger or if they're equal.

5. Frequently Asked Questions (FAQ)

Q1: Why use cross-multiplication instead of decimal conversion?
A: Cross-multiplication gives exact results without rounding errors that can occur with decimal conversion.

Q2: What if denominators are equal?
A: With equal denominators, you can simply compare numerators directly.

Q3: Does this work for improper fractions?
A: Yes, the method works for all fractions - proper, improper, and mixed numbers (when converted to improper form).

Q4: Can I compare more than two fractions?
A: This calculator compares two fractions at a time. For multiple fractions, find a common denominator or convert to decimals.

Q5: What about negative fractions?
A: The method works but remember negative numbers have opposite comparison rules (e.g., -1/2 is greater than -3/4).
