To determine if the ratios of purple mixtures made by Aria and Cody are equivalent, we can compare the ratios of blue to red in each mixture.

Aria's mixture:

  • Blue : Red = 7 tbsp : 2 tbsp
  • This can be expressed as the ratio 7/2.

Cody's mixture:

  • Blue : Red = 21 tbsp : 6 tbsp
  • This can be expressed as the ratio 21/6.

Now, we can simplify Cody's ratio:

  • 21/6 = 7/2 (by dividing both the numerator and denominator by 3).

Since both Aria and Cody have the same ratio of blue to red (7/2), their mixtures are indeed equivalent.

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