Ratio is 3:2. For every 3 cups of white paint she uses she uses in the mixture, she needs to use 2 cups of red paint.

To find out how much red paint she needs if she uses a certain amount of white paint, you can use the given ratio of 3:2. Let's call the amount of white paint "x".

According to the ratio, for every 3 cups of white paint, she needs 2 cups of red paint. So, for "x" cups of white paint, she would need (2/3) times "x" cups of red paint.

Let's calculate an example:
If she uses 6 cups of white paint, we can substitute "x" with 6 in the equation.
Red paint needed = (2/3) * 6 = 4 cups.

So, if she uses 6 cups of white paint, she would need 4 cups of red paint.

You can use this method to calculate the required amount of red paint for any given amount of white paint using the given ratio.

Yes.
