To determine if Aria's and Cody's ratios of purple mixture are equivalent, we can simplify each person's paint mixture ratio.

Aria uses 7 tbsp. of blue to 2 tbsp. of red, which gives us the ratio of:

  • Blue : Red = 7 : 2

Cody uses 21 tbsp. of blue to 6 tbsp. of red, which gives us the ratio of:

  • Blue : Red = 21 : 6

Next, we simplify Cody's ratio:

  • Divide both parts of the ratio by 3:
    • 21 ÷ 3 = 7
    • 6 ÷ 3 = 2

So, Cody's simplified ratio is:

  • Blue : Red = 7 : 2

Since both Aria's and Cody's simplified ratios are 7 : 2, we can conclude that their ratios of purple mixture are equivalent.

Thus, the correct response is: Yes, they are equivalent.
