What are complex fractions

The video tutorial introduces rational and complex fractions, explaining that complex fractions involve fractions in the numerator, denominator, or both. It provides examples to illustrate these concepts and discusses the main operation of division in complex fractions. The tutorial also covers methods to solve complex fractions by combining them into a single fraction, highlighting the differences from rational expressions. The video concludes with a summary of the key points discussed.

In the expression 3 / (x / 2), what makes it a complex fraction?

• It is a simple fraction.

• The denominator is a fraction.

• The numerator is a whole number.

• It has a variable in the numerator.

What is the first step in solving a complex fraction?

• Subtract the fractions.

• Add the fractions together.

• Combine the fractions into a single fraction.
