1. Warm Up: Find the Least Common Denominator (LCM)

2. 9-5 Addition, Subtraction, and Complex Fractions

3. Ex 1: Perform the indicated operation a. b. Note: In order to add or subtract 2 fractions, we must have the SAME DENOMINATOR.

4. Ex 2: Find the LCD a. b. Ask yourself: Do the denominators have any factors in common? In this example, there are no common factors. (You can leave it “unsimplified.”) Factor! Note: Use ALL of the factors!

5. Ex 3: Perform the indicated operation, then simplify Frist: Find the LCD Multiply each fraction by the factors it doesn’t already have.

6. Ex 4: Perform the indicated operation and simplify.

7. Exit Slip: Perform the indicated operation and simplify.
