Answer:
Mixture 1 and Mixture 2 will create the same color
Explanation:
we know that
If two mixtures create the same color, then the proportion of the painting in the mixtures must be the same
Let
x ----> the ounces of a red paint in the mixture
y ----> the ounces of a blue paint in the mixture
Verify the proportion of the paints in each mixture
Mixture 1) x=2, y=1

Mixture 2) x=7, y=3.5

Mixture 3) x=4.5, y=2

Mixture 4) x=5.5, y=2.5

therefore
Mixture 1 and Mixture 2 will create the same color, because have the same ratio
