Understanding Operations

Finding Common Denominators

To add or subtract fractions with different denominators, find the Least Common Multiple (LCM). This creates equal-sized pieces you can combine. Use our GCD & LCM Calculator to find the LCM of denominators.

Simplification Process

To simplify a fraction, divide both the numerator and denominator by their Greatest Common Divisor (GCD). We use the Euclidean Algorithm for efficient calculation. Our GCD & LCM Calculator can help you find the GCD for simplification.

Frequently Asked Questions

Q:How do I add fractions with different denominators?

To add fractions with different denominators: 1) Find the Least Common Multiple (LCM) of the denominators. 2) Convert each fraction to an equivalent fraction with the LCM as the denominator. 3) Add the numerators and keep the common denominator. 4) Simplify the result if possible.

Q:How do I simplify a fraction?

To simplify a fraction, divide both the numerator and denominator by their Greatest Common Divisor (GCD). For example, to simplify 8/12, find GCD(8,12) = 4, then divide: 8÷4 / 12÷4 = 2/3.

Q:What is the difference between a proper fraction and an improper fraction?

A proper fraction has a numerator smaller than the denominator (e.g., 3/4). An improper fraction has a numerator equal to or larger than the denominator (e.g., 5/4 or 4/4). Improper fractions can be converted to mixed numbers.

Q:How do I convert a mixed number to an improper fraction?

Multiply the whole number by the denominator, then add the numerator. Place this sum over the original denominator. Example: 2 3/4 = (2×4 + 3)/4 = 11/4.
