Answer:
2/3 cups of grape juice would be needed for 1 gallon of punch.
Step-by-step explanation:
Since the punch recipe requires 2 cups of
grape juice to make 3 gallons of punch.
To find the amount of grape juice needed to make 1 gallon of punch, let represent the amount of grape juice needed with x for simplicity and we cross multiple the equations to the get the value of x, which is the amount of grape juice needed to make 1gallon of punch.
i.e
2 cups of grape juice = 3gallons of punch.
x cups of grape juice = 1 gallon of punch
Cross multiple
3x = 2
Divide both side by 3
3x/3 = 2/3
x = 2/3
Therefore
2/3 cups of grape juice would be needed for 1 gallon of punch.
