Answer: 2/3yards
Explanation:
From the question, we are informed that Jill is making a long cape and that she needs 7 1/3yards of blue fabric for the outside of the cape and that she needs 6 2/3yards of purple fabric for the lining of the cap.
To calculate the yards of blue fabric that'll be needed more than purple fabric,, we subtract 6 2/3 from 7 1/3. This will be:
= 7 1/3 - 6 2/3
= 2/3
She needs 2/3yards of blue fabric more.
