Odpowiedź:
a) ( 3 i 3/4 + 2 i 1/8) :5= ( 3 i 6/8 + 2 i 1/8):5= 5 i 7/8*1/5= 47/8*1/5= 47/40=
= 1 i 7/40
b) 6 i 1/8 :4 +2 i 3/4= 6 i 1/8 *1/4 + 2 i 3/4= 49/8 *1/4 + 2 i 3/4=
= 49/32 + 2 i 3/4= 1 i 17/32 +2 i 24/32= 3 i 41/32= 4 i 9/32
c) 3 i 1/6 + 2 i 1/3 : 3= 3 i 1/6 + 7/3*1/3 = 3 i 1/6 + 7/9=
= 3 i 3/18 + 14/18= 3 i 17/18
d) ( 4 i 3/5 -2 i 1/2) : 2= ( 4 i 6/10- 2 i 5/10) *1/2= 2 i 1/10*1/2=
= 21/10*1/2 = 21/20 = 1 i 1/20
