Hunter-Best [27]

Answer:

Tom will need $\dfrac{5}{4}$ gallons of fruit drink.

Step-by-step explanation:

Hint- This question can be solved by unitary method.

Tom has a recipe for punch that calls for $\dfrac{1}{2}$ gallon of fruit drink.

i.e for 1 batch of the punch Tom needs $\dfrac{1}{2}$ gallon of fruit drink.

For $\dfrac{5}{2}$ batch of the punch Tom needs $\dfrac{1}{2}\times \dfrac{5}{2}=\dfrac{5}{4}$ gallons of fruit drink.

Therefore, Tom will need $\dfrac{5}{4}$ gallons of fruit drink.
