whats the scale factor if these polygons are proportional?

please answer in a format like: prop, s.f.= 1:4 
 
1. A = 2, 6, 8, 9 B = 4, 12, 16, 18
 
2. A = 2, 3, 6, 10 B= 6, 9, 18, 30
 
3. A = 7, 10, 14, 15 B = 17.5, 25, 35, 37.5
 
4. A = 4, 4, 5, 6 B = 1.2, 1.2, 1.5, 1.8
 
5. A = 9, 10, 16, 19 B = 41.4, 46, 73.6, 87.4

Hey Carol, I appreciate your help, and im sorry, but I should have clarified what I needed. I posted the other questions to show an example of what I needed the answers to look like, because my problem with number 6 is that none of the available answers seem to be correct, and I was wondering if my answer was right, and I just needed to format it a certain way or something. for question 6, which asks what the scale factor is if A = 4, 9, 10, 14 B = 4.8, 10.8, 12, 16.8

AProp, s.f. = 0.227
BProp, s.f. = 0.756
CProp, s.f. = 0.841
D Prop, s.f. = 0.621
E Prop, s.f. = 0.124
F Prop: s.f. = 0.833 
 
But the answer I got was 1.2 am I doing something wrong, or are the answers wrong? im sorry, i should have clarified, and im sorry for wasting your time. You don't have to answer this if you don't want to, i'll just rephrase the question and post it again if thats okay. Im new to this site, im sorry if im an annoyance.
