3) $12 frac{13}{48}-(9 frac{17}{32}-4 frac{5}{24})=12 frac{26}{96}-9 frac{51}{96}+4 frac{20}{96}=16 frac{46}{96}-9 frac{51}{96}=15 frac{142}{96}-9 frac{51}{96}=6 frac{91}{96}$
4) $(18 -10frac{18}{35})-(3 frac{9}{28}+2 frac{3}{20})=(17 frac{35}{35} -10frac{18}{35})-(3 frac{45}{140}+2 frac{21}{140})=7 frac{25}{35}- 5 frac{66}{140}=7 frac{50}{70}- 5 frac{33}{70}=2frac{17}{70}$
