Complex fractions are fractions with a fractional numerator, denominator, or both.
Given,
We have to state about complex fraction;-
Complex fraction;
When both the denominator and the numerator, or both, contain fractions, the fraction is said to be complicated. A complex fraction with a variable is a complex rational expression. For instance: The complex fraction 4/(1/3) has the denominator as 1/3 and the numerator as 4.
Solving the complex fraction;
In the numerator and denominator, make a single fraction. By multiplying the numerator by the inverse or reciprocal of the denominator, you can use the fractional division rule. If it's required, simplify.
