Answer:
In order: There are potentially many solutions, but the one I know that will work with this is 2 blue spaces, 1 Green Space, 2 Orange Spaces, and 5 Red Spaces.
Explanation:
How I came to my answer was simple. I divided the greatest common factor into every number of spins, and that number would be the amount of spaces for each.
With this, we get the following equations, as listed below.
16 divided by 8, which accounts for both Orange and Blue.
40 divided by 8, which will account for Red.
8 divided by 8, which accounts for Green.
This gives us our solutions as listed in the Answer Section.
Hope this helped.
