Plz give me 5 multiplication fractions with the answer

(a/b)(c/d)=(ac/bd)

Therefore:
(5/4).(2/5)=(5*2)/(4*5)=10/20=1/2
(3/8).(-1/2)=(3*(-1)) /(8*2)=-3/16
(2/5)(5/2)=(2*5)/(5*2)=10/10)=1
(1/2)(1/3)=1/6
(-1/4)(-2/3)=[(-1)*(-2)] / (4*3)=2/12=1/6

2/4 x2/4=4/16
7/4 x5/2=35/8
1/2 x20/18=20/36
2/5 x3/4=6/20
1/2 x1/3=2/6

Is there a picture of a graph or whatever that goes along with this?

Ithink it's b sorry if i'm wrong
