Lesson Excerpt:

- “Let’s begin dividing rational expressions. The easiest way to learn about how to do this is to work through an example. Here is one for us to start with.”
- On Board: 16b
8
- “Now in looking at this problem, the expression is the numerator. If I was going to talk through this problem, I would say that the expression 16b is divided by 8. The easiest way to think about this is to divide 8 into 16. There isn’t another variable to divide the b by, so it must stay just like it is.”
