Answer:
5/7 yards
Explanation:
To find the total amount of fabric Holly needs, we need to add the amount of patterned fabric and the amount of solid colored fabric she needs.
Total fabric = patterned fabric + solid colored fabric
Total fabric = 3/7 yards + 2/7 yards
Total fabric = 5/7 yards
Therefore, Holly needs a total of 5/7 yards of fabric.
