${t^{-1/2}+t^{1/2}\over{t^2}} =$

The expression $q-1\over q-4$ can be written as $1 + {(\; )\over(\; )}$. What is the $(\; )\over(\; )$ term?

${3\over x+2}+{2x\over x^2-x-6} =$

$\displaystyle{{1\over x+y}\over x+y} =$

$\displaystyle{{w+1\over2}\over w+1} =$

${2x(x^3+1)^2-2x^2(x^3+1)(3x^2)\over((x^3+1)^2)^2} =$

${1\over 2r+3}-{3\over 4r^2+6r} =$

${1\over x+1}-{1\over x-1} =$

${{1\over(x+h)^2}-{1\over x^2}\over h} =$

$u+a+{u\over u+a} =$
