Lecture 15 (Intermediate Algebra) Rational Expressions

To simplify a complex fraction (a fraction containing fractions in its numerator and/or denominator), the lecture's approach is to:

1. A.Cross-multiply the outer numerator with the outer denominator
2. B.Simplify the numerator and the denominator separately, then divide by multiplying by the reciprocal
3. C.Distribute every term across every other term until no fractions remain
4. D.Take the reciprocal of the entire expression to flip it right-side up
