Answer 1

Odpowiedź:

1 i 5/6 + 2 i 2/3 + 1 i 14/9 =  1 5/6 + 2 6/9 + 1 14/9 = 1 5/6 + 3 20/9 =

= 1 15/18 + 5 2/9 = 1 15/18 + 5 4/18 = 6 19/18 = 7 1/18

1 i 3/8 + 2 i 1/3 + 1 i 5/6 =  1 9/24 + 2 8/24 + 1 20/24 = 3 17/24 + 1 20/24 =

= 4 37/24 = 513/24

2 i 7/10 + 1 3/4 + 4/5 =  2 7/10 + 8/10 + 1 3/4 = 2 15/10 + 1 3/4 = 3 5/10 + 1 3/4 =

= 3 1/2 + 1 3/4 = 3 2/4 + 1 3/4 = 4 5/4 = 5 1/4
