Easy Medium Hard Simplify Complex Fractions

Brian McLogan13 minutes read

Complex fractions involve finding the least common multiple of denominators, then multiplying each expression to simplify the fraction by eliminating fractions. Factors like trinomials and binomials can be simplified in a medium complexity example by identifying the least common multiple and rewriting negative powers as reciprocals to avoid fractions in the denominator.

Insights

  • Complex fractions involve fractions in both the numerator and denominator, requiring the elimination of fractions by finding the least common multiple of the denominators.
  • When simplifying complex fractions, factor trinomials and binomials, identify the least common multiple of the denominators, rewrite negative powers as reciprocals, and apply the distributive property to combine like terms for a comprehensive simplification process.
