The ratio of flour to water to sugar in a recipe is 11:8:1. The ratio in a new recipe calls for a doubling of the ratio of flour to water from the original recipe and a halving of the ratio of flour to sugar. If the new recipe calls for 4 cups of water, how much sugar is required?
{ "A": "5", "B": "4", "C": "3", "D": "2", "E": "1" }
multiply(divide(4, 8), multiply(const_4, 1))
divide(n3,n1)|multiply(n2,const_4)|multiply(#0,#1)|
"the ratio of flour to water is 22 : 8 = 11 : 4 . the ratio of flour to sugar is 5.5 : 1 = 11 : 2 . the new ratio of flour to water to sugar is 11 : 4 : 2 if we need 4 cups of water , then we need 2 cups of sugar . the answer is d ."
