Fraction Calculator
Add, subtract, multiply, or divide fractions and get results as fractions and decimals.
The Fraction Calculator lets you perform arithmetic operations on two fractions quickly and accurately. Whether you need to add, subtract, multiply, or divide fractions, this tool handles it all.
How It Works
Enter the numerator and denominator for each fraction, select your operation, and the calculator instantly computes the result. Results are shown as both a simplified fraction and a decimal value.
Fraction Arithmetic Rules
- Addition/Subtraction: Find a common denominator, then add or subtract the numerators.
- Multiplication: Multiply numerators together and denominators together.
- Division: Multiply the first fraction by the reciprocal of the second.
The result is automatically reduced to its simplest form using the greatest common divisor (GCD). This calculator is invaluable for students, teachers, and anyone working with fractional values in everyday math or professional contexts.
Frequently Asked Questions
How do I add fractions with different denominators?
The calculator automatically finds a common denominator before adding. For example, 1/2 + 1/3 becomes 3/6 + 2/6 = 5/6.
Does the calculator simplify fractions?
Yes, all results are automatically reduced to their simplest form using the greatest common divisor.
Can I divide by a fraction that equals zero?
No. If the second fraction equals zero (numerator is 0), division is undefined and the calculator will show an error.
