Answer 1

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

Answer 2

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