So, half again as much as 2 cups is 2 cups plus 1 cup = 3 cups of plenta. Dr. Robert J. Rapalje Answer by oberobic(2304)   (Show Source): You can put this solution on YOUR website!You can use the method of 'like ratios'. We are told that the ratio of water to polenta is 2 to 1/2, which can be shown as: 2/.5 We are told that we're interested in how much for 3/4 c. of polenta. So that ratio will be x/.75. The ratios have to be equal, so we need to solve: 2/.5 = x/.75 Cross multiplying, we arrive at 2(.75) = x(.5) 1.5 = .5x Dividing by .5 1.5/.5 = x x = 1.5/.5 x = 3
