Answer 1

A) 2i1/2+(2i1/2)=2i1/2-2i1/2=0
b) -3i1/4+7i1/2=-13/4+15/2= -13/4+30/4=17/4=4i1/4
c) -12i5/7+5i1/14=-89/7+71/14= -178/14+71/14=-107/14=-7i9/14
d) 12i3/4-5i5/6=51/4-35/6= 153/12-70/12=83/12=6i11/12
e) 6i1/6-8i1/6=-2
f)-4i3/4-6i1/8=-19/4-49/8= -38/8-49/8=-87/8=-11i7/8
g) 1i7/15-(-25i2/5)=22/15+127/5= 22/15+381/15=403/15=26i13/15
h) -2i4/13+(-4i27/39)= -30/13-183/39=-90/39-183/39= -273/39=-7
i) -3i3/8-(-12i1/8)=-27/8+97/8= 70/8=8i6/8
