Answer:
[tex]\dfrac{8}{3}\ \text{cups of orange juice}[/tex] or [tex]2\dfrac{2}{3}\ \text{cups of orange juice}[/tex] is used
Step-by-step explanation:
Daniel uses the proportions of [tex]\dfrac{2}{3}[/tex] cups of orange juice and [tex]\dfrac{1}{4}[/tex] cups of carrot juice to make a mixed juice.
Now, in the question 1 cup of carrot juice is used. So 4 times of the proportion of the carrot juice is used. Accordingly 4 times of the cups of orange juice will be used.
[tex]\dfrac{2}{3}\ \text{cups of orange juice}=\dfrac{1}{4}\ \text{cups of carrot juice}\\\Rightarrow 4\times \dfrac{2}{3}\ \text{cups of orange juice}=4\times \dfrac{1}{4}\ \text{cups of carrot juice}\\\Rightarrow \dfrac{8}{3}\ \text{cups of orange juice}=1\ \text{cup of carrot juice}[/tex]
So for one cup of carrot juice [tex]\dfrac{8}{3}\ \text{cups of orange juice}[/tex] or [tex]2\dfrac{2}{3}\ \text{cups of orange juice}[/tex] is used.
