Answer 1

a) (-0,1)+(+8 1/3)+(-11 2/3)+(+4,4) = 4,3 - 3 1/3 = 4 9/30 + 3 10/30 = 7 19/30

 

 

b) 5,2+(-o,6)+(+3/5)+(-3,2) = 2

 

Answer 2

a) = -1/10+25/3-35/3+44/10= (-1/10+44/10)+(25/3-35/3)= 129/30-100/30=29/30

b) = 52/10-6/10+3/5-3/2= (52/10-6/10)+(6/10-15/10)= 46/10-9/10=37/10=37/10

Answer 3

a.  (-0,1)+(+8 1/3)+(-11 2/3)+(+4,4) = 4,3 + -3 i 1/3 = 4 i 3/10 - 3 i 1/3 =

4i9/30  - 3 i 10/30 = 3 i 39-30 - 3 i 3 i 10/30 = 19/30

 

b. 5,2 +(-0,6)+(3/5)+(-3,2) = 5i2/10+(-6/10)+3/5+(3i1/5)=  4i6/10+6/10+3i2/10 = 5i 2/10 + 3i2/10 = 8 i 4/10 = 8,4
