Question

Grace is painting her room. She created a mixture with 2 cups of blue paint for every 3 cups of white. If she decides to make a larger mixture and uses 4.5 cups of white paint, how much blue paint will she use? ​

Answer 1

The answer is 3. If you find the unit rate of white to blue paint and multiply it by 4.5 it would come out to 3.000007 or something minute like that.
