Answer 1

a) 29/5 - 3/1 * 1/3 +1/2 = 29/5-3/3+1/2=58/6-6/6+3/6=55/6=90i 1/6

b) 3 i 3/7 - (-4/1) * (-4/1) = 3 i 3/7 -16 = -12i4/7

c) =- 25/40+(-19/4)*1/2 = -25/4 - 19/8 = (-50/8) -19/8 = (-69/8) = (-8 i 5/8)

 

d) -39/7+1/3-2/50*(-1/2)=-4095/105+35/105+21/105=-4039/105=38 i 49/105

e)= -4/3-1/4-1/6=-32/24-6/24-4/24=42/24= 1 i 3/4

Answer 2

a)5i4/5-3*1/3+1/2=2i4/5*2/6+3/6=2i4/5*5/6=14/5*5/6=14/6=2i2/6=2i1/3

b)3i3/7-(-4):(-1/4)=3i3/7+4:(-1/4)=7i3/7*(-4/1)=24/7*(-4/1)=96/7=13i5/7

c)-6i1/4+(-4i3/4)*1/2=-25/4-19/4*1/2=-44/4*1/2=-22/4=-5i2/4=-5i1/2

d)-5i4/7+1/3-2/5*(-1/2)=-39/7+1/3-2/5*(-1/2)=-117/21+7/21-2/5*(-1/2)=-110/21-2/5*(-1/2)=-550/105-42/105*(-1/2)=592/105*(-1/2)=592/210

e)-1i1/3-1/4+1/2*(-1/3)=-16/12-3/12+6/12*(-1/3)=-13/12*(-1/3)=-13/36
