MAT1275FinalReviewFall2019version
This problem requires you to simplify a complex fraction. Recall that there are two methods for doing this:
Method 1: simplify the “top” and the “bottom” of the complex fraction by adding or subtracting, if necessary; then turn the division into multiplying by the reciprocal of the “bottom”.
Method 2: Find the LCM of ALL the denominators in the “top” and “bottom” of the complex fraction; multiply the “top” and “bottom” by this LCM to clear all the “little” denominators; simplify and turn the division into multiplying by the reciprocal.
In any case it goes without saying that you must reduce your final answer to lowest terms.
Resources:
• WeBWorK on ComplexFractions:  there are two of them, one for Method 1 and one for Method 2.  (Use “Show Me Another” if you have already completed these.)
• Video showing how to use each of those methods to solve #3a
You may also need to review how to find the LCM. Here is a tutorial from VirtualNerd on finding Least Common Denominators to add/subtract rational expressions
