[tex]\frac{8}1-1\frac{11}{16}=(8-1)-\frac{11}{16}=6\frac{16-11}{16}=\boxed{6\frac{5}{16}}[/tex]

[tex]1\frac{3}5+1\frac{1}4=(1+1)+\frac{3}5+\frac{1}4=2+\frac{3\cdot4+5}{4\cdot5}=\boxed{2\frac{17}{20}}[/tex]

[tex]5\frac{1}4-1\frac{1}8=(5-1)+(\frac{1}4-\frac{1}8)=4+\frac{2-1}{8}=\boxed{4\frac{1}8}[/tex]
