We’ve moved on to the next phase of the rational expressions unit: Complex Fractions. Don’t be intimidated by their name! These are expressions that involve “nested fractions,” meaning the numerator and denominator of the expression are both fractions (or a sum/difference of fractions) themselves.

Remember the basic process for simplifying these beastly expressions:

- Combine fractions in the numerator (finding a lowest common denominator and so on) so you have one single rational expression
- Combine fractions in the denominator (LCD, etc.)
**Keep**the top fraction,**flip**the bottom fraction, and**change**the operation to multiplication (KFC)- Simplify.
