Allright, here's the last problem I need help with, thanks to all those that have helped! Solve:
[(3/x^2)+(1/x)]/[2-(4/5x)]
Thanks! You guys rock!

$\displaystyle \frac{\frac{3}{x^2}+\frac{1}{x}}{2-\frac{4}{5x}}$
so we want to multiply both the denominator and numerator by the LCD $\displaystyle 5x^2$
$\displaystyle \frac{5x^2}{5x^2} \left( \frac{\frac{3}{x^2}+\frac{1}{x}}{2-\frac{4}{5x}} \right)$
after we distribute we get
$\displaystyle \frac{15+5x}{10x^2-4x}=\frac{5(x+3)}{2x(5x-2)}$
