Answer:
The third figure shows a proportional relationship between weight and price.
Step-by-step explanation:
In first figure both given weight and price are not proportional as 1.5 is 3/4th of 2 and 4.5 is 1/2nd of 9.
In second figure also both weight and price are not proportional.
In third figure 5 is 10th time of 0.5 and 7.50 is also 10th time of 0.75, also both has same unit. So, it is in proportional relationship.
In fourth figure only numbers are in proportional relationship but units are different. So, we can't say that it is in proportional relationship.
