i got lost in complex fractions. i don't know how to input equations here..
Hello princess_21Sorry, I can't understand your attached document. But have another look at the one you've already visited
http://www.mathhelpforum.com/math-he...fractions.html
If you're still really stuck, can you write one out neatly by hand, and either scan it or take a digital photo, and attach that instead?

indeed. just to flesh it out a bit
$\displaystyle \displaystyle \frac {1 - \frac 1{m - 1}}{1 + \frac 1{m - 1}} \cdot {\color{red} \frac {m - 1}{m - 1}} + \frac {1 - \frac 1{1 + \frac 1{m - 1}} \cdot {\color{red} \frac {m - 1}{m - 1}}}{1 - \frac 1{1 - \frac 1{m-1}} \cdot {\color{red} \frac {m - 1}{m - 1}}}$
$\displaystyle = \frac {m - 1 - 1}{m - 1 + 1} + \frac {1 - \frac {m - 1}{m - 1 + 1}}{1 - \frac {m - 1}{m - 1 - 1}}$
$\displaystyle = \frac {m - 2}m + \frac {1 - \frac {m - 1}m}{1 - \frac {m - 1}{m - 2}}$
now perform a similar trick on the second fraction as i did before and continue
