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

${0.07\over M}+{3\over4}M^2 =$

${1\over x^{-2}+y^{-2}} =$

${\left(4-(x+h)^2\right)-\left(4-x^2\right)\over h} =$

${r+2\over r+1}+1 =$

${u+c\over u}-c =$

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

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

${x^2-a^2\over x^2+2xa+a^2} =$

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