Answer:

{ \boxed { \sf{Answer = 16 \frac{9}{44} }}}

Step-by-step explanation:

\\  \sf {7} \frac{3}{4}  + (12 - 3 \frac{6}{11} )

\\  \sf =  \frac{31}{4}  + (12 -  \frac{39}{11} )

\\  \sf =  \frac{31}{4} ( \frac{132 - 39}{11} )

\\  \sf =  \frac{31}{4}  +  \frac{93}{11}

\\  \sf =  \frac{341 + 372}{44}

\\  \sf =  \frac{713}{44}

\\  \sf = 16\frac{9}{44}
