Answer:
Table 1 and Table 3
Explanation;
For us to know thw table having equivalent ratios between x and y, we will find the ratio x/y for the tables as shown;
For table 1;
x/y = 3/12 = 5/20 = 2/8
x/y = 1/4 = 1/4 = 1/4
Since they have the same ratios, hence table 1 shows equivalent ratios between x and y
For table 3;
x/y = 6/4 = 9/6 = 12/8
x/y = 3/2 = 3/2 = 3/2
Since they have the same ratios, hence table 3 also shows equivalent ratios between x and y
