You mix 1/2 cup of red paint for every 1/4 cup of blue paint to make 12 cups of purple paint. How much red paint and
blue paint do you use?

4 cups of blue paint and 8 cups of red paint

explanation

to pour one cup of blue paint, two cups of red paint has to be poured.
since when you add both those it adds to 3
so multiply each by 4 to get 4 cups of blue paint and 8 cups of red paint

Ithink it is correct but just ask someone else but i am sure it it
