1. What is Fraction Subtraction?

Fraction subtraction is a mathematical operation that finds the difference between two fractions. The standard method involves finding a common denominator and then subtracting the numerators.

2. How Does the Calculator Work?

The calculator uses the 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 calculates the equivalent numerators, subtracts them, and simplifies the result if possible.

3. Importance of Fraction Subtraction

Details: Understanding fraction subtraction is fundamental in mathematics and essential for solving problems in algebra, physics, engineering, and everyday measurements.

4. Using the Calculator

Tips: Enter all four values (two numerators and two denominators). 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 denominators are the same?
A: If denominators are equal (b = d), you can simply subtract numerators: (a - c)/b.

Q2: How are negative fractions handled?
A: Negative signs can be in numerator, denominator, or before the fraction. The calculator properly handles all cases.

Q3: What if the result is an improper fraction?
A: The calculator shows the exact fractional result. You may convert to mixed numbers if desired.

Q4: Can I subtract whole numbers with fractions?
A: Yes, treat whole numbers as fractions with denominator 1 (e.g., 5 = 5/1).

Q5: What about subtracting mixed numbers?
A: First convert mixed numbers to improper fractions, then use the calculator.
