A recipe for pie crust calls for 2/3 cup of water for every 3 cups of flour. If you doubled the recipe, you would need 1 1/3 cup
s of water for 6 cups of flour. Which proportions involving complex fractions could represent these ratios? Check all that apply. 1. StartFraction two-thirds over 6 EndFraction = StartFraction four-thirds over 3 EndFraction
2. StartFraction two-thirds over 3 EndFraction = StartFraction four-thirds over 6 EndFraction
3. StartFraction 6 over two-thirds EndFraction = StartFraction 3 over four-thirds EndFraction
4. StartFraction 6 over four-thirds EndFraction = StartFraction 3 over two-thirds EndFraction
