Решите задачу:

$\left(-6\frac17+5\frac34\right):\frac{11}{14}-\left(-3\frac34+1\frac56\right):\frac16\\\\1)\;-6\frac17+5\frac34=-6\frac4{28}+5\frac{21}{28}=-\frac{172}{28}+\frac{161}{28}=-\frac{11}{28}\\2)\;-3\frac34+1\frac56=-3\frac9{12}+1\frac{10}{12}=-\frac{45}{12}+\frac{22}{12}=-\frac{23}{12}\\3)\;-\frac{11}{28}:\frac{11}{14}=-\frac{11}{28}\cdot\frac{14}{11}=-\frac12\\4)\;-\frac{23}{12}:\frac16=-\frac{23}{12}\cdot6=-\frac{23}2\\5)-\frac12-\left(-\frac{23}2\right)=-\frac12+\frac{23}2=\frac{22}2=11$
