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.
