-12

Step-by-step explanation:
-5(1)/(2)-9(1)/(4)+2(3)/(4)

first we convert to improper fraction:


=(-11)/(2)\text{ - }(37)/(4)\text{ + }(11)/(4)

simplify:


\begin{gathered} =\text{ }\frac{2(-11)\text{ - 37(1) + 11(1)}}{4} \\ =\text{ }\frac{-22\text{ - 37 + 11}}{4} \\ =\text{ }\frac{-59\text{ + 11}}{4} \end{gathered}
\begin{gathered} =\text{ }(-48)/(4) \\ =\text{ -12} \end{gathered}
