Answer 1

1) (2 i 1/4 + 5/12)/(2 i 1/4 - 5/12)= (9/4 + 5/12)/(9/4- 5/12)= (27/12 + 5/12)/ (27/12-5/12)= (32/12) / (22/12)= 32/22
2) (1 i 2/3 * 4 i 1/2) - ( (3 i 1/2) / (2 i 1/2)) = ((5/3) * (9/2))-((7/2)/(5/2))=(45/6)-(7/5)=(225/30)-(42/30)=183/30

Answer 2

(2 1/4+5/12):(2 1/4-5/12)=(2 3/12+5/12):(2 3/12-5/12)=2 8/12:1 10/12=32/12:22/12=32/12*12/22=16/11=1 5/11

(1 2/3*4 1/2)-(3 1/2:2 1/2)=(5/3*9/2)-(7/2:5/2)=15/2-(7/2*2/5)=15/2-7/5=75/10-14/10=61/10
