Simplifying Complex Fractions Methods

The video tutorial explains how to simplify complex fractions using two methods. The first method involves simplifying the numerator and denominator separately, then rewriting the complex fraction as a division problem and multiplying by the reciprocal. The second method uses the least common denominator (LCD) to simplify the fractions. Both methods result in the same simplified form of the complex fraction, and the video provides detailed steps and examples for each approach.

What is the first step in simplifying a complex fraction using Method 1?

• Find the least common denominator.

• Simplify the numerator and denominator if possible.

• Multiply by the reciprocal.

• Distribute the denominator.
