To compare the ratios of the purple mixture, we need to simplify it.
For Aria, the ratio of blue to red is 7 tbsp. to 2 tbsp. In simplest form, this is 7:2.
For Cody, the ratio of blue to red is 21 tbsp. to 6 tbsp. We can simplify this by dividing both numbers by 3: 21/3 = 7 and 6/3 = 2. So the simplified ratio for Cody is also 7:2.
Therefore, the ratios of their purple mixtures are equivalent to one another's.
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)
