Answer 1

A)8/3-1/2- I1 5/6I=8/3-1/2- 11/6= (16-3-11)/6=2/6=1/3

B)I2 3/8-7/2-5/4I=I19/8-7/2-5/4I=I(19-28-10)/8I=I-19/8I=19/8

C)I3 1/4-5/6-8/3I=I13/4-5/6-8/3I=I(39-10-32)/12I=I-3/12I=3/12=1/4

D)I4 1/5-8/3-(-13/15)I=I21/5-8/3+13/15I=I(63-40+13)/15I=36/15=12/5

E)7/18-1 2/9-(-11)=7/18-11/9+11=(7-22+198)/18=183/18=61/6

F)11/20-13/4-(-I2 3/5I)=11/20-13/4-(-I13/5I)=11/20-13/4-(-13/5)=
=11/20-13/4+13/5=(11-65+52)/20=-2/20=-1/10
