12
32
4.5
12.5

Answer 1

The question requires finding the consistent ratio in milliliters of a red to yellow paint mix to continue the proportional relationship for a shade of orange. By confirming the 1:2 ratio from provided examples, we can then exclude or confirm the appropriate missing values.

Step-by-step explanation:

The question asks to identify missing values in a table that displays a proportional relationship between milliliters of red and yellow paint to create a certain shade of orange. To find the proportion, we take the given ratios of red to yellow paint and look for consistency in the ratios. For instance, 10.5 mL of red paint corresponds to 28 mL of yellow paint, which simplifies to a 3:7 or 1:2 ratio after dividing by 3.5. If we apply the same ratio to the other pairs, 7.5 mL of red paint should correspond to 20 mL of yellow paint, which indeed also simplifies to a 3:7 or 1:2 ratio, confirming the proportional relationship.
