Final answer:
To find the number of cups of orange juice in 1 serving, set up a proportion and solve for x.
Step-by-step explanation:
To find the number of cups of orange juice in 1 serving, we can use a proportion.
Since the recipe calls for 1/3 cup of orange juice to make 5/6 serving of fruit smoothie, we can set up the proportion:
1/3 cup / 5/6 serving = x cups / 1 serving
To solve for x, we can cross-multiply and divide:
1/3 x 1 serving = 5/6 x cups
x = (5/6) / (1/3)
x = 5/6 x 3/1
x = 15/6
x = 2.5 cups
So, there are 2.5 cups of orange juice in 1 serving of the fruit smoothie.
