Question

To create a 5 gallon bucket of GRAY paint, I mixed 3 gallons of BLACK paint and 2 gallons of WHITE paint. If I had a GRAY paint mixture with 9 gallons of BLACK paint in it. How many gallons of WHITE must it have in it?

Answer 1

Answer:

6 gallons

Step-by-step explanation:

It would be 6 gallons because if you see, the black paint is 9 gallons. In the first sentence, you said 3 gallons. So, I times that by 3, to make it 9. So, then you do the same thing with the white paint. 2 x 3 = 6 gallons of white paint.
