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


\stackrel{mixed}{12(1)/(2)}\implies \cfrac{12\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{25}{2}} ~\hfill \stackrel{mixed}{7(1)/(4)} \implies \cfrac{7\cdot 4+1}{4} \implies \stackrel{improper}{\cfrac{29}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{25}{2}-\cfrac{29}{4}\implies \cfrac{(2)25~~ - ~~(1)29}{\underset{\textit{using this LCD}}{4}}\implies \cfrac{50-29}{4}\implies \cfrac{21}{4}\implies 5(1)/(4)
