1. What is Fraction Subtraction?

Fraction subtraction involves finding the difference between two fractions. To subtract fractions, they must have a common denominator, which is achieved by finding the least common multiple of the denominators or simply multiplying the denominators together.

2. How Does the Calculator Work?

The calculator uses the fraction subtraction formula:

\[ \frac{a}{b} - \frac{c}{d} = \frac{a \times d - b \times c}{b \times d} \]

Where:

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: Mastering fraction subtraction is essential for algebra, measurements, ratios, and real-world applications like cooking, construction, and financial calculations.

4. Using the Calculator

Tips: Enter numerators and denominators as integers. Denominators must be positive numbers. The calculator will show the result in both unsimplified and simplified forms when possible.

5. Frequently Asked Questions (FAQ)

Q1: Can I subtract fractions with different denominators?
A: Yes, this calculator automatically finds a common denominator by multiplying the denominators together.

Q2: What if my result is an improper fraction?
A: The calculator will display the improper fraction and its simplified form. You can convert it to a mixed number if needed.

Q3: How does the simplification work?
A: The calculator uses the greatest common divisor (GCD) to reduce the fraction to its simplest form.

Q4: What if I enter negative numbers?
A: Negative numerators are allowed and will be handled correctly. Denominators must remain positive.

Q5: Can I use this for mixed numbers?
A: First convert mixed numbers to improper fractions, then use the calculator.
