If in a fraction, the numerator or the denominator or both are fractions, then it is called a complex fraction.
Example 1:
[tex]\frac{\frac{3}{4} }{7}[/tex]
Here, since the numerator is a fraction, it is a complex fraction.
Example 2:
[tex]\frac{\frac{1}{2} }{\frac{3}{7} }[/tex]
Here, since the numerator and the denominator are fractions, it is a complex fraction.
