To find the whole part ratio of the total refreshments in the box of orange juice as a fraction, we first need to determine the total amount of refreshments available and then create a fraction comparing the orange juice to the total refreshments.
- Calculate the total number of refreshments:
- Lemonades: 13
- Bottles of water: 14
- Boxes of orange juice: 12
Total refreshments = 13 (lemonades) + 14 (water) + 12 (orange juice) = 39 refreshments
-
The whole part (number of boxes of orange juice) is 12.
-
Now, we can form the fraction of orange juice to total refreshments: \[ \text{Fraction} = \frac{\text{Boxes of orange juice}}{\text{Total refreshments}} = \frac{12}{39} \]
So, the answer is \(\frac{12}{39}\). Hence, the correct answer choice is:
12/39.
