Answer 1

$1\dfrac{7}{12}+5\dfrac{6}{7}\div\bigg(2\dfrac{2}{5}-3\dfrac{4}{7}\bigg)=\bold{-3\dfrac{5}{12}}$

$1) \: \: 2\dfrac{2}{5}-3\dfrac{4}{7}=\dfrac{12}{5}-\dfrac{25}{7}=\dfrac{84}{35}-\dfrac{125}{35}=-\dfrac{41}{35}$

$2) \: \: 5\dfrac{6}{7}\div\bigg(-\dfrac{41}{35}\bigg)=\dfrac{41}{7}\cdot\bigg(-\dfrac{35}{41}\bigg)=-5$

$3) \: \: 1\dfrac{7}{12}+(-5)=\dfrac{19}{12}-5=1\dfrac{7}{12}-4\dfrac{12}{12}=-3\dfrac{5}{12}$
