Answer 1

a) 24 i 5/6 +11 i 1/3-[(5 i 3/4 +(29 i 1/6-1 i 1/12)]=29 i 2/12 - 1 i 1/12 = 28 i 1/12

5 i 3/4 + 28 i 1/12 = 5 i 9/12 + 28 i 1/12 = 33 i 5/6

24 i 5/6 +  11 i 1/3 - 33 i 5/6 = 24 i 5/6 + 11 i 2/6 - 33 i 5/6 = 2 i 2/6 = 2 i 1/3

 

b)12 i 5/8 - 5 i 13/16 +(3 i 3/4 -9/16) = 3 i 3/4 - 9/16 = 3 i 12/16 - 9/16 = 3/16

12 i 5/8 - 5 i 13/16 + 3/16 = 12 i 10/16 - 5 13/16 + 3/16  = 7

 

c)11 i 11/12 -(3 i 1/2 - 1 i 2/3) +(21 i 3/4 - 1 i 5/6)= 3 i 3/6 - 1 i 4/6 = 1 i 5/6

21 i 9/12 - 1 i 10/12 = 19 i 11/12

11 i 11/12 - 1 i 5/6 + 19 i 11/12 = 11 i 11/12 - 1 i 10/12 + 19 i 11/12 = 30

 

d)22 i 2/3 + 19 i 3/4 - 2 i 5/12= 22 i 8/12 + 19 i 9/12 - 2 i 5/12= 40
