Simplifying Complex Fractions

The video tutorial covers the topic of simplifying complex fractions. It begins with an introduction to complex fractions, explaining that they have fractions in both the numerator and the denominator. The teacher then demonstrates how to simplify two examples of complex fractions using the conventional method, which involves finding the least common denominator (LCD) and performing arithmetic operations. The video concludes with a task for students to solve a similar problem and encourages them to engage with the content by leaving their answers in the comments.
