Cody and Aria are painting a mural. They decide they want part of the mural to have a purple background. Aria uses 7 tbsp. of blue to 2 tbsp. of red to make her purple paint. Cody is planning to use more and uses 21 tbsp. of blue to 6 tbsp. of red. Are their ratios of purple mixture equivalent to one another's?(1 point)

No, Cody’s has more blue.
No, Cody’s has more blue.
Yes, they are equivalent.
To compare the ratios of the purple mixture, we need to simplify them.
Aria's ratio: 7 tbsp. of blue to 2 tbsp. of red.
Cody's ratio: 21 tbsp. of blue to 6 tbsp. of red.
To simplify Aria's ratio, we divide both parts by the greatest common divisor, which is 1:
7/1 : 2/1
To simplify Cody's ratio, we divide both parts by the greatest common divisor, which is 3:
21/3 : 6/3
Simplifying both ratios, we get:
7/1 : 2/1 = 7 : 2
21/3 : 6/3 = 7 : 2
Therefore, their ratios of the purple mixture (7:2) are equivalent to each other, so the correct answer is: Yes, they are equivalent.
