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
