When the second number is divided by the first, the result is ...

First table
9/3 = 3
12/4 = 3
20/5 = 4 . . . . result is not consistent. NOT a proportional relationship

Second table
25/20 = 1.25
30/24 = 1.25
40/32 = 1.25 . . . . result is consistent. A PROPORTIONAL RELATIONSHIP

Third table
12/4 = 3
15/5 = 3
24/6 = 4 . . . . result is not consistent. NOT a proportional relationship

Fourth table
4/3 ≈ 1.33
9/6 = 1.5
16/12 ≈ 1.33 . . . . result is not consistent. NOT a proportional relationship
