Unit 1: Limits and Continuity Option 3: Complex Fractions Method: Complex Fraction Limits

Make one clean fraction.

Step 1: Try Option 1: Plug it in.

Step 2: Start by adding or subtracting any fractions in the top or bottom of your complex fraction.

Step 3: The apply the division of fractions rewrite (Copy-Dot-Flip).

Step 4: Simplify the equation.

Do NOT look to multiply everything together. Instead look for common factors between the top and bottom that you are able to cancel out.

Step 5: Go back to Option 1: Plug it in.
