To find the constant of proportionality, we can compute the ratio of purple paint to yellow paint for one pair of values in the table. Let's take the first pair: 2 cups of purple paint and 6 cups of yellow paint.
The ratio of purple paint to yellow paint is 2/6 = 1/3.
Since this ratio is constant for all pairs in the table, we can conclude that the constant of proportionality between purple and yellow paint is 1/3.
Therefore, the answer is: A) 1/3.
