A. a b/ c = ac+ b/c
A. a b/ c = ac+ b/c
B) A/B =AD/BD
=AD/BD
C) A/B * C/D= AC/BD
C) A/B * C/D= AC/BD
D) A/B DIVEDED C/D = A/b * D/C= AD/BC
D) A/B DIVEDED C/D = A/b * D/C= AD/BC
MULTIPLICATION AND DIVISION. EXP. A/B IS THE SAME AS B/A

b. By converting to a decimal form, we get 2.1 + = 2.1+0.5=2.6
c. 3+2i –(5+10i)=3+2i –5–10i = 3–5+2i–10i = -2–8i
b. By converting to a decimal form, we get 2.1 + = 2.1+0.5=2.6
c. 3+2i –(5+10i)=3+2i –5–10i = 3–5+2i–10i = -2–8i
