Mixture A has 3 cups of white paint and 9 cups of green paint. Mixture B has 7 cups of white paint and 21 cups of green paint. Is Mixture A darker, lighter, or the same color as Mixture B?

Answer: I would say that it is the same color.
Step-by-step explanation:
3 cups of white and 9 cups of green.
7 cups of white and 27 cups of green.
Imagine a green marker and a bunch of piece of paper. Make a green circle of a sheet of paper and put another on top. Repeat the process until there are 3 pieces of paper with 9 green circles and 7 seven pieces of paper with 27 green circles.
