2What is a complex fraction? A complex fraction is fraction with another fraction in the numerator or denominator.Ex.
3So how can we simplify them? Remember, fractions are just division problems.We can rewrite the complex fraction as a division problem with two fractions.This division problem then changes to multiplication by the reciprocal.
4What if we have mixed numbers in the complex fraction? If we have mixed numbers, we treat it as an addition problem with unlike denominators.We want to be working with two fractions, so make sure the numerator is one fraction, and the denominator is one fractionNow we can rewrite the complex fraction as a division of two fractions
7What about complex rational expression? Treat the complex rational expression as a division problemAdd any rational expressions to form rational expressions in the numerator and denominatorFactorSimplify“Bad” values
