Dr. Fraser covers Complex Fractions and begins with mixed expressions and an analogy to mixed fractions. You will then learn how to convert mixed expressions to rational expressions. After, you will cover complex fractions as well as how to simplify these complex fractions. Four extra video examples end this lecture.
fraction is a fraction with one or more fractions in the
numerator or the denominator (or both).
If a complex
fraction consists of one fraction divided by another fraction,
simplify the complex fraction by dividing the fraction in the
numerator by the fraction in the denominator: invert the fraction
in the denominator and multiply it by the fraction in the numerator.
If the expression
in either the numerator or denominator of the complex fraction
consists of a sum or difference of fractions, carry out that sum or
difference first and simplify the result. Then simplify the
resulting complex fraction using the technique described above.
