let's firstly convert the mixed fractions to improper fractions.


\stackrel{mixed}{5(1)/(2)}\implies \cfrac{5\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{11}{2}}~\hfill \stackrel{mixed}{1(3)/(7)} \implies \cfrac{1\cdot 7+3}{7} \implies \stackrel{improper}{\cfrac{10}{7}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{11}{2}+\cfrac{10}{7}\implies \cfrac{(7)(11)~~ + ~~(2)(10)}{\underset{\textit{using this LCD}}{14}}\implies \cfrac{77+20}{14}\implies \cfrac{97}{14}\implies {\Large \begin{array}{llll} 6(13)/(14) \end{array}}
