Answer: 1 1/12 yards
Explanation:
Since Ciara needs 2 ⅓ yards of fabric for the shawl and also needs 1 ¾ yards of fabric for the dress, the total yards needed will be:
= 2⅓ + 1¾
= 2 4/12 + 1 9/12
= 3 13/12
= 4 1/12 yards
Since she has 3 yards of fabric, the number of yards needed more will be:
= 4 1/12 - 3
= 1 1/12
Therefore, she needs 1 1/12 yards more.
