Start to convert the mixed numbers into fractions


2(1)/(2)=(5)/(2)
\begin{gathered} 1(1)/(4)=(5)/(4) \\ 7(1)/(12)=(85)/(12) \end{gathered}

then by the order of the operations, we make the division


((5)/(2))/((5)/(4))=(5\cdot4)/(5\cdot2)=2

then,


\begin{gathered} 3-2+7(1)/(12) \\ 1+7(1)/(12) \\ 1+(85)/(12) \\ (97)/(12) \end{gathered}
