Answer 1

a) 6/7*1i1/2:1i1/3=6/7*3/2:4/3=3/7*3*3/4=27/28

b) 1i5/6:3i2/3*1i17==11/6:11/3*8/7=11/6*3/11*8/7=1/2*1*8/7=8/14=4/7

c) [(3/8+1/6):3i1/4]-(1/3)³=[(9/24+4/24):13/4]-1/27=13/24*4/13-1/27=1/6-1/27=

=9/54-2/54=7/54

d) (1/2)³*2i2/3:1i1/6=1/8*8/3:7/8=1/3*6/7=2/7

e) 1i1/4*6-3:1i1/5=5/4*6-3:6/5=5/2*3-3*5/6=15/2-5/2=10/2=5

f)1i3/8:3/4:1i2/9=11/8*4/3:11/9=11/2*1/3*9/11=1/2*3=3/2=1i1/2

g)4i3/8-1i2/3:3i3/4=35/8-5/3*4/15=35/8-1/3*4/3=35/8-4/9=315/72-32/72=283/72=3i67/72
