Answer 1

1) $(8-4\frac{3}{11})+2\frac{8}{11}=(3\frac{11}{11}-\frac{3}{11})+2\frac{8}{11}=3\frac{8}{11}+2\frac{8}{11}=5\frac{16}{11}=6\frac{5}{11}$

2) $11\frac{1}{7}-(5\frac{4}{7}+3\frac{6}{7})=11\frac{1}{7}-8\frac{10}{7}=11\frac{1}{7}-9\frac{3}{7}=2\frac{1}{7}-\frac{3}{7}=1\frac{8}{7}-\frac{3}{7}=1\frac{5}{7}$

Answer 2

 (8-4 3/11)+2 8/11= 3 8\11+2 8\11=6  5\11

 11 1/7-(5 4/7+3 6/7)= 11  1\7-9  3\7=1  5\7
