Fraction Addition Tool

Understanding Fraction Addition

Fractions represent parts of a whole and consist of a numerator (top number) and a denominator (bottom number). To add fractions, especially with different denominators, you need to find a common denominator. This involves finding the least common multiple (LCM) of the denominators. Once you have a common denominator, you can add the numerators and keep the denominator the same. Finally, simplify the resulting fraction if possible by dividing both the numerator and the denominator by their greatest common divisor (GCD). This tool simplifies adding three fractions, making it easy to get accurate results quickly.

• Numerator: The number above the fraction line, indicating parts of a whole.
• Denominator: The number below the fraction line, indicating the total parts in the whole.
• Common Denominator: A shared multiple of the denominators, necessary for fraction addition.
• LCM (Least Common Multiple): The smallest common multiple of two or more numbers, used as the common denominator.
