Answer:
In order to use all the paint in a paint mixture in the same ratio of 1:5, the painter needs 2.4 ounces of paint thinner
Explanation:
The given parameters are;
The number of parts of thinner used to create 5 parts of paint mixture = 1 part
The amount of paint the painter has = 12 ounces
The amount of thinner is given by the relation;
Ratio of thinner to paint mixture = 1:5
Which gives, 1 part of thinner is required for 5 parts of paint mixture
1/5 parts of thinner is required for 1 part of paint mixture
Therefore, 12/5 or 2.4 parts of thinner will be required for 12 parts of paint mixture
Which gives;
2.4 ounces of thinner will be required for 12 ounces of paint mixture
Therefore, in order to use all the paint in a paint mixture in the same ratio of 1:5, the painter needs 2.4 ounces of thinner.
