Final answer:
Ms. Perry used a total of 7 5/12 gallons of juice to make the fruit punch, combining 4 2/3 gallons of cranberry juice and 2 3/4 gallons of raspberry juice. Therefore correct option is C
Step-by-step explanation:
The question asks us to find the total amount of juice used to make a fruit punch by adding together 4 2/3 gallons of cranberry juice and 2 3/4 gallons of raspberry juice.
We start by converting these mixed numbers into improper fractions to make addition easier:
- 4 2/3 gallons becomes (4×3) + 2 = 14/3 gallons
- 2 3/4 gallons becomes (2×4) + 3 = 11/4 gallons
Next, we add these two improper fractions. To do so, we need a common denominator. The least common multiple of 3 and 4 is 12, so we convert both fractions to have a denominator of 12:
- 14/3 becomes (14×4)/(3×4) = 56/12
- 11/4 becomes (11×3)/(4×3) = 33/12
Now, we can add the two fractions:
56/12 + 33/12 = (56+33)/12
= 89/12 gallons
Finally, we convert this improper fraction back to a mixed number:
89/12 = 7 gallons 5/12 gallons
Therefore, Ms. Perry used 7 5/12 gallons of juice to make the fruit punch, which corresponds to answer choice c. 7 5/12 gallons.
