Addition and Subtraction of Fractions

This section explains the fundamental process of adding and subtracting fractions with different denominators. The method requires finding a common denominator before performing the operation.

Definition: When adding or subtracting fractions with different denominators, you must first convert them to equivalent fractions with the same denominator.

Example: The process is demonstrated with 3/8 + 5/6, where:

1. Find common multiple of denominators (8 and 6)
2. Convert fractions to equivalent forms (9/24 + 20/24)
3. Add numerators while keeping the common denominator (29/24)

Highlight: The key step is identifying the least common multiple of the denominators to minimize calculations.

Vocabulary: Common denominator - the shared bottom number that allows fractions to be added or subtracted.
