Answer 1

***
$4- frac{5}{8} =3 frac{8}{8} -frac{5}{8} =3 frac{3}{8}$
***
$5- frac{3}{5} =4 frac{5}{5} - frac{3}{5} =4 frac{2}{5}$
***
$3 frac{3}{9} -2 frac{5}{8}=3 frac{3*8}{9*8}-2 frac{5*9}{8*9}=3 frac{24}{72}-2frac{45}{72}=2 frac{96}{72} -2 frac{45}{72} =$
$= frac{51}{72} = frac{51:3}{72:3} = frac{17}{24}$
***
$8 frac{5}{7} - 5frac{9}{6} =8 frac{5}{7} -6 frac{3}{6} =8 frac{5}{7} -6 frac{3:3}{6:3}=8 frac{5}{7} -6 frac{1}{2}=$
$8 frac{5*2}{7*2} -6 frac{1*7}{2*7}=8 frac{10}{14} -6 frac{7}{14} =3 frac{3}{14}$
