Answer:
6.66 yards of ribbon (rounded to two decimal places)
Explanation:
If Julie has 10 yards of ribbon and divides it into 3 equal pieces, each piece will be 10 / 3 = 3.33 yards long (rounded to two decimal places).
Julie uses 2 of these pieces on gifts, so she uses 2 * 3.33 = 6.66 yards of ribbon (rounded to two decimal places) on the gifts.
