proszę o rozpisanie działania a nie sam wynik

Answer 1

a) 6 - 2 i 2/3 - 3 i 1/6 + 3/4= 6/1-8/3- 19/6+3/4=9/12- 32/12- 38/12+9/12=-23/12-29/12=-52/12=-4 1/3

 

b) 2 i 2/9 - 3 i 5/6 + 5 i 1/3=20/9- 23/6+ 16/3= 120/54- 207/54+288/54=

=-87/54+288/54=201/54= 3 13/18

Answer 2

a = 3 i 1/3 - 3 i 1/6 + 3/4 = 3 i 2/6 - 3 i 1/6 + 3/4 =1/6 + 3/4 = 2/12 + 9/12 = 11/12
b = 2 i 4/18 - 3 i 15/18 + 5 i 1/3 = ( - ) 1 i 11/18 + 5 i 6/18 = 3 i 5/18
