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?

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.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
