Question

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)

Answer 1

To determine if their ratios are equivalent, we need to compare the ratio of blue to red in both mixtures.

Aria's ratio of blue to red is 7:2.
Cody's ratio of blue to red is 21:6.

We can simplify both ratios to their simplest terms:

Aria's ratio of blue to red simplifies to 7:2.
Cody's ratio of blue to red simplifies to 7:2 as well.

Since both ratios simplify to the same ratio of 7:2, their ratios of purple mixture are equivalent to one another's.
