С действиями

Answer 1

$left(-6frac17+5frac34right):frac{11}{14}-left(-3frac34+1frac56right):frac16\\1);-6frac17+5frac34=-6frac4{28}+5frac{21}{28}=-frac{172}{28}+frac{161}{28}=-frac{11}{28}\2);-3frac34+1frac56=-3frac9{12}+1frac{10}{12}=-frac{45}{12}+frac{22}{12}=-frac{23}{12}\3);-frac{11}{28}:frac{11}{14}=-frac{11}{28}cdotfrac{14}{11}=-frac12\4);-frac{23}{12}:frac16=-frac{23}{12}cdot6=-frac{23}2\5)-frac12-left(-frac{23}2right)=-frac12+frac{23}2=frac{22}2=11$
