Answer 1

$\frac{7}{3}:(\frac{15}{24}-\frac{64}{24})-2*\frac{10}{7}=\frac{7}{3}*(-\frac{24}{49})-\frac{20}{7}=-\frac{8}{7}-\frac{20}{7}=-\frac{28}{7}=-4$

Answer 2

2 1/3:(5/8-8/3)-2•1 3/7=-4
1)5/8-8/3=15/24-64/24=-49/24
2)2 1/3:(-49/24)=7/3:(-49/24)=-8/7
3)2•1 3/7=2/1•10/7=20/7
4)-8/7-20/7=-28/7=-4
