Answer:
Sally need [tex]5\frac{1}{3}[/tex] cups of orange juice.
Step-by-step explanation:
Given:
Sally makes a fruit drink using ⅔ of a cup of orange juice for every ¼ of a cup of pineapple juice.
If she uses 2 cups of pineapple juice.
Now, to find the cups of orange juice.
So, to solve by using unitary method:
As, ¼ of a cup of pineapple juice is needed for orange juice of = ⅔ cup.
So, 1 cup of pineapple juice is needed for orange juice of = [tex]\frac{2}{3}\div \frac{1}{4}[/tex]
[tex]=\frac{2}{3}\times \frac{4}{1}[/tex]
[tex]=\frac{8}{3}[/tex] cups.
Thus, 2 cups of pineapple juice is needed for orange juice of = [tex]\frac{8}{3} \times 2[/tex]
= [tex]\frac{16}{3}[/tex]
= [tex]5\frac{1}{3}[/tex] cups.
Therefore, Sally need [tex]5\frac{1}{3}[/tex] cups of orange juice.
