Simplifying complex fractions

The video tutorial explains how to simplify a complex fraction by determining the least common denominator (LCD) and using it to eliminate fractions. The instructor presents two methods: finding common denominators for the numerator and denominator separately or using a single LCD for all terms. The video demonstrates the latter method, showing how multiplying each term by the LCD simplifies the expression by eliminating fractions, resulting in a simplified form of the original complex fraction.

Why is it important to keep fractions equivalent when multiplying by the LCD?

What are the final terms left after simplifying the complex fraction?
