$5)3:1\frac{1}{2} +5:1\frac{1}{4} =3:1,5+5:1,25=2+4=6\\\\6)10\frac{2}{3} -5\frac{1}{3} :3\frac{1}{5} =10\frac{2}{3} -\frac{5}{3} =9\frac{5}{3} -\frac{5}{3} =9\\\\7) (10\frac{2}{3} -5\frac{1}{3} ):3\frac{1}{3} =5\frac{1}{3} :3\frac{1}{3} =1,6\\\\8)4\frac{1}{2} *\frac{8}{9} -5\frac{1}{3} :10\frac{2}{3} =\frac{9}{2} *\frac{8}{9}-\frac{16}{3} :\frac{32}{3} =4-0,5=3,5\\\\9)0,7*1,3+5,1:0,17=0,91+30=30,91\\\\10)3,38-2,24:1,25=3,38-1,792=1,588\\\\11)(3,38-2,24):1,25=1,14:1,25=0,912$

$12)31,7:63,4-23,4:11,7=0,5-2=-1,5$
