Answer 1

1) = - 7 i 3/30 - 4 i 14/30= - 11 i 17/30

2) = - 6 i 1/12 + 3 i 7/16= - 6 i 4/48 + 3 i 21/48 = - 3 i 25/48

3) = - 4.75 - 4.2 = - 8 .95

4) = - 9.64 + 7.928= - 2.288

5) = - 50/7 : ( - 4/25) = - 50/7 razy (-4/25) = 8/7 =  1 i 1/7

6) = -25/6 : ( - 8/3) = - 25/6 razy (-3/8)=25/16= 1 i 9/16

7) =-8 ,4 razy (-10/64)=-84/10 razy (-10/64)=84/64=1 i 20/64

8) = 3.18

9) = - 7 i 4/36 - 3 i 21/36= - 6 i 40/36-3i21/36=-9i 61/36
