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



\stackrel{mixed}{3(1)/(2)}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} ~\hfill \stackrel{mixed}{1(4)/(8)} \implies \cfrac{1\cdot 8+4}{8} \implies \stackrel{improper}{\cfrac{12}{8}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{7}{2}+\cfrac{12}{8}\implies \cfrac{(4)7~~ + ~~(1)12}{\underset{\textit{using this LCD}}{8}}\implies \cfrac{28+12}{8}\implies \cfrac{30}{8}\implies \cfrac{15}{4}\implies 3(3)/(4)
