Answer:
All we need to do is to find the persentage of gray paint and when we have the number we can easily multiply it by 1 gallon again.
So we have:
48/80 · 100 = 60%
Therefore, we know that 60% of the paint is gray paint.
Now we multiply 1 gallon by 60% which will gives us the answer of 0.60 gallons.
So for every one gallon of paint, there are 0.60 gallons of gray paint and the left is white paint.
