Answer 1

4 i 5/9 + 2 i 1/3 x 4 i 1/2 = 4 i 5/9 + 7/6 x 9/2 = 4 i 5/9 + 21/2 = 4 i 5/9 + 10 i 1/2 = 4 i 10/18 + 10 9/18 = 14 i 19/18 = 15 i 1/18

 

1 i 4/9 - 6 : 4 i 2/3 = 1 i 4/9 - 6/1 : 14/3 = 1 i 4/9 - 6/1 x 3/14 = 1 i 4/9 - 9/7=

= 1 i 28/63 - 81/63 = 1 i 109/63 = 2 i 46/63

 

3 i 1/2 x ( 2 i 1/4 - 1 i 1/2 : 6 ) =3 i 1/2 x ( 2 i 1/4 - 3/2 : 6/1 ) =

= 3 i 1/2 x ( 2 i 1/4 - 3/2 x 1/6) = 3 i 1/2 x (2 i 1/4 - 1/4) =

= 3 i 1/2 x 2 = 7/2 x 2/1 = 7/1 = 7

 

5 i 2/9 - 1 i 1/2                          = 5 i 2/9 - 1 i 1/2                    =

             3 i 2/3 x ( 1 i 1/4 - 1/2)                 3 i 2/3 x (5/4 - 2/4)

= 5 i 2/9 - 1 i 1/2         = 5 i 2/9 - 1 i 1/2     = 5 i 2/9 - 1 i 1/2 =

                3 i 1/2 x 3/4                7/2 x 3/4                 21/8

= 5 i 2/9 - 1 i 1/2 : 21/8 = 5 i 2/9 - 3/2 x 8/21 =

= 5 i 2/9 - 4/7 = 5 i 14/63 - 36/63 = 4 i 77/63 - 36/63 = 4 i 41/63
