Answer:
1/2 cups of apple juice David used for 1 cup of carrot juice
Step-by-step explanation:
David uses 1/4 cups of apple juice for every 1/2 cup of carrot juice to make a fruit drink.
Two 1/2 cups of carrot juice makes 1 cup of carrot juice
because [tex]\frac{1}{2} + \frac{1}{2} = \frac{2}{2} =1[/tex]
For each 1/2 cups of carrot juice David used 1/4 cups of apple juice
For 1 cup of carrot juice , two 1/2 cups of carrot juice used
so two 1/4 cups of apple juice should be used for 1 cup of carrot juice
[tex]\frac{1}{4} + \frac{1}{4} = \frac{2}{4} =\frac{1}{2}[/tex]
