1) Quantity A = 5, Quantity B = 20
Ratio = Quantity B / Quantity A = 20 / 5 = 4
2) Quantity A = 10, Quantity B = 40
Ratio = Quantity B / Quantity A = 40 / 10 = 4
As we can see, in both cases, the ratios are equal to 4.
Thus, since the ratio of the quantities remains constant (equal to 4) for different values in the table, we can conclude that the table represents a proportional relationship.
