Option D

ANSWER:  

9 scoops of red sand for every 6 scoops of blue sand maintains the ratio Ross wants.

SOLUTION:

Given, Ross is making colored sand for an art project.  

He mixes 3 scoops of red sand for every 2 scoops of blue sand.

First, let us calculate the ratio of given information.

ratio of red sand to blue sand = 3 : 2

Now, let us check the options.

A. 12 scoops of red sand for every 9 scoops of blue sand

Here, ratio of red sand to blue sand = 12 : 9 = 4 : 3

This ratio does not matches with our ratio. So this is not correct option.

B. 10 scoops of red sand for every 8 scoops of blue sand  

Here, ratio of red sand to blue sand = 10 : 8 = 5 : 4

This ratio does not matches with our ratio. So this is not correct option

C. 8 scoops of red sand for every 12 scoops of blue sand  

Here, ratio of red sand to blue sand = 8 : 12 = 2 : 3

This ratio does not matches with our ratio. So this is not correct option

D. 9 scoops of red sand for every 6 scoops of blue sand

Here, ratio of red sand to blue sand = 9 : 6 = 3 : 2

This ratio matches with our ratio. So this is correct option.

Hence, correct option is D.
