Answer 2

$\left[2-\left(-\frac{5}{2} \right):\left(\frac{11}{4} \right) \right].\left(\frac{11}{4} \right)=\\\\\left[2-\left(-\frac{5}{2} \right).\left(\frac{4}{11} \right) \right].\left(\frac{11}{4} \right)=\\\\\left[2-\left(-\frac{20}{22} \right) \right].\left(\frac{11}{4} \right)=\\\\\left(2+\frac{20}{22} \right).\left(\frac{11}{4} \right)=\\\\\left(\frac{44+20}{22} \right).\left(\frac{11}{4} \right)=\\\\\frac{64}{22}.\frac{11}{4}=\\\\\frac{704}{88}=\boxed{8}$
