What is this?
A Fraction Calculator is a mathematical tool used to perform operations with fractions such as addition, subtraction, multiplication, and division. It also helps simplify fractions, convert between fractions and decimals, and calculate mixed numbers easily.
How to Use the Fraction Calculator
A fraction calculator helps you perform arithmetic operations with fractions including
addition, subtraction, multiplication, division, and simplification. Fractions represent
parts of a whole and are essential in mathematics, cooking, measurements, and many
practical applications.
The calculator handles complex fraction operations automatically, providing simplified
results and helping you understand fractional relationships and calculations.
1. Enter the Numerator and Denominator
Input the numerator (top number) and denominator (bottom number) for each fraction.
You can enter whole numbers, mixed numbers, or improper fractions.
2. Select the Operation
Choose the arithmetic operation you want to perform: addition (+), subtraction (-),
multiplication (×), or division (÷).
3. Click Calculate
Submit the form to let the calculator perform the operation and simplify the result
automatically.
4. Review the Results
Examine the calculated result, both as an improper fraction and mixed number if applicable.
Use this information for mathematical problems, recipes, or measurements.
Key Formulas Used in the Calculator
Adding Fractions
To add fractions, find a common denominator, add the numerators, and keep the denominator the same. For example, 1/2 + 1/3 = (3 + 2)/6 = 5/6.
Subtracting Fractions
To subtract fractions, find a common denominator, subtract the numerators, and keep the denominator the same. For example, 3/4 - 1/2 = (6 - 4)/8 = 2/8 = 1/4.
Multiplying Fractions
To multiply fractions, multiply the numerators together and the denominators together. For example, 2/3 × 3/4 = (2×3)/(3×4) = 6/12 = 1/2.
Dividing Fractions
To divide fractions, multiply by the reciprocal of the second fraction. For example, 2/3 ÷ 3/4 = 2/3 × 4/3 = 8/9.
Simplifying Fractions
A fraction is simplified by dividing both numerator and denominator by their greatest common divisor (GCD). For example, 12/18 simplifies to 2/3 by dividing both by 6.
