Final answer:
Using the Distributive Property, multiply 3 3/5 yards of fabric per costume by 5 costumes to get 18/5 × 5, which simplifies to 18 yards total for 5 costumes.
Step-by-step explanation:
To calculate the total amount of fabric needed for 5 butterfly costumes using the Distributive Property, we multiply the amount of fabric needed for one costume by the number of costumes.
Each costume requires 3 3/5 yards of fabric, which can also be written as 18/5 yards when converted to an improper fraction. Now, we use the Distributive Property to find the total fabric needed for 5 costumes:
18/5 yards per costume × 5 costumes = (18 × 5) / 5 yards = 90/5 yards = 18 yards.
Therefore, the total number of yards of fabric needed for 5 costumes is 18 yards.
