Answer 1

$(5 frac{7}{11} -3 frac{5}{6} ):1 frac{53}{66} =(5 frac{7*6}{11*6} -3 frac{5*11}{6*11} ):frac{66*1+53}{66} = \ \ \ =(5 frac{42}{66} -3 frac{55}{66} ): frac{119}{66} =(4 frac{42+66}{66} -3 frac{55}{66} ): frac{119}{66} = \ \ \ =1 frac{53}{66} * frac{66}{119} = frac{119:119}{66:66} * frac{66:66}{119:119} = frac{1}{1} * frac{1}{1} =1*1=1$
