Answer:
4 1/12 yards of fabric left.
Step-by-step explanation:
First things first: convert the mixed numbers so they have the same denominator
The least common multiple of 4 and 3 is 12, so the common denominator will be 12.
So Jenna has 10 9/12, and uses 6 8/12.
Now subtract:
10 9/12 - 6 8/12 = 4 1/12
So there is 4 1/12 yards of fabric left.
