Thank you Ms. Sue!

A complex fraction is a fraction in which either the numerator or the denominator (or both) contains a fraction. Here's an example of a complex fraction:

(1/2) / (3/4)

In this example, both the numerator and the denominator are fractions. The numerator is 1/2, and the denominator is 3/4. Therefore, (1/2) / (3/4) is a complex fraction.
