Apitcher her could hold two twelfths of a gallon of water. if roger filled up nine pitchers, how much water would he have

Well, you if a pitcher holds  of a gallon of water, and Roger filled up nine pitchers, you would multiply, however, drawing it out would be the best answer. If you draw nine pitchers, then you would count by 2. Then it would make 6 pitchers to make a gallon. So then you would have 3 left over. So you would have 1. So you would have 1 1/2 gallons of water.
