3 i 1/2 - 3 i 1/6 : (-2 i 1/9) = 3 i 1/2 - 19/6 : (-19/9) = 3 i 1/2 - 19/6 * (-9/19) = 3 i 1/2 - (-9/6) =
3 i 1/2 + 3/2 = 3 i 1/2 + 1 i 1/2 = 5
[tex]3\frac{1}{2}-3\frac{1}{6}:(-2\frac{1}{9})=3\frac{1}{2}-\frac{19}{6}:(-\frac{19}{9})= 3\frac{1}{2}-\frac{19}{6}*(-\frac{9}{19})=\\= 3\frac{1}{2}+\frac{3}{2}=3,5+1,5= 5[/tex]
