Answer 1

$frac{1}{ frac{1}{96} + frac{1}{112} } = frac{ frac{1}{13} }{672} = frac{672}{13} = 51 frac{9}{13}$

Answer 2

$frac{1}{frac{frac{1}{2} }{48}+frac{frac{1}{2} }{56}} =frac{1}{frac{1}{2} *frac{1}{48}+frac{1}{2}*frac{1}{56}} =frac{1}{frac{1}{96} +frac{1}{112}} =frac{1}{frac{13}{672}} =frac{672}{13} =51frac{9}{13}$
