Now finally, is there anything you don't get?

there are several ways to do problems like these, especially the ones where you have to combine fractions. i may do it a different way from you professor. if so, is my way confusing, would you rather a different method on any of them? give me feedback - April 3rd 2007, 05:35 PMccynd
it was just that one question.. but I figured out from the way you did it,

the way he was showing.

That was all my questions for now.. I may have some more later,

if so I'll probly post them again.

Thanks so much for your help!! :) :D - April 3rd 2007, 05:37 PMJhevon
well, number 4 isn't an equation. you have to be careful when multiplying through when you don't have an equation. if no equation exists, you have to multiply by something over itself, which is the same as multiplying by 1, so it doesn't change the value in the end. in the case of number 4, you would multiply (x-1)/5 by 2/2, which is 1, but it turns it into (2x-2)/10, which has the same denominator as the other fraction, this way, you don't have to worry about an LCM, it would just be 10, and you just worry about adding the tops. and there are still more ways to combine fractions

So i am to assume that you understand EVERYTHING that i did?
