1. What is Fraction Subtraction?

Fraction subtraction is a mathematical operation that finds the difference between two fractions. The result is another fraction that represents how much larger the first fraction is compared to the second.

2. How Does the Calculator Work?

The calculator uses the standard fraction subtraction formula:

Where:

• \( a \) — Numerator of first fraction
• \( b \) — Denominator of first fraction
• \( c \) — Numerator of second fraction
• \( d \) — Denominator of second fraction

Explanation: The calculator first finds a common denominator by multiplying the denominators, then subtracts the adjusted numerators, and finally simplifies the result if possible.

3. Importance of Fraction Subtraction

Details: Fraction subtraction is fundamental in mathematics, used in algebra, calculus, and real-world applications like cooking, construction, and financial calculations.

4. Using the Calculator

Tips: Enter numerators and denominators for both fractions. Denominators must be positive integers. The calculator will display the result in both unsimplified and simplified forms (if simplification is possible).

5. Frequently Asked Questions (FAQ)

Q1: What if my denominators are different?
A: The calculator automatically handles different denominators by finding a common denominator.

Q2: Can I subtract mixed numbers?
A: Convert mixed numbers to improper fractions first (e.g., 1½ becomes 3/2).

Q3: What if my result is negative?
A: A negative result means the second fraction was larger than the first.

Q4: How does simplification work?
A: The calculator divides numerator and denominator by their greatest common divisor (GCD).

Q5: What if I enter zero as denominator?
A: The calculator requires denominators to be positive integers (minimum 1).
