Dexter and Jay are using a gallon of white paint to paint the walls. Dexter used 3/8 of the gallon of paint while Jay used 5/8 of a gallon of paint. If a gallon is equal to 4 liters, how many liters of paint were left from Dexter and Jay combined? Let's be accurate as possible.
Dexter used 4 x 3 / 8 = 3 / 2 liters of paint. Jay used 4 x 5 / 8 = 5 / 2 liters of paint. Together, they used 3 / 2 + 5 / 2 = 4 liters of paint. Since each of them used a gallon of paint, then they both used 2 x 4 = 8 liters of paint together. Therefore, 8 - 4 = 4 liters of paint were left.
The answer: 4.
