Ответ:
9 gallons
Step-by-step explanation:
Given: Ratio of colors in painting:
4 parts blue, 3 parts red, and 3 parts green.
Total parts = 4+3+3 =10
Fraction of blue =![\dfrac{\text{Number of parts of blue}}{\text{total parts}}=\dfrac{4}{10}](/tpl/images/0928/4773/6f99a.png)
Since, Quantity of blue color used = 12 gallons
Let total quantity of color be x,
Total color used = 30 gallons
Color used for green part only =![\dfrac{3}{10}\times30 = \text{9 gallons}](/tpl/images/0928/4773/0a700.png)
Hence, 9 gallons of paint were needed for the green part of the painting.
