The given expression is

First, we transform each mixed number into a fraction

$\begin{gathered} 7(1)/(2)=(7\cdot2+1)/(2)=(14+1)/(2)=(15)/(2) \\ 4(3)/(4)=(4\cdot4+3)/(4)=(16+3)/(4)=(19)/(4) \end{gathered}$

Then, we subtract

$(15)/(2)-(19)/(4)=(15\cdot4-2\cdot19)/(2\cdot4)=(60-38)/(8)=(22)/(8)=2(3)/(4)$
