Answer:
8
Step-by-step explanation:
Total length of the fabric is 
We need to find the number of scarves can she make if she needs 5/6 of a yard for each scarf.
Let she needs x scarves. So, ATQ

Hence, she can make 8 scarves.
So we need to compare them at the sam ounches
find the least common multiple (the smallest number that they will both multiply into)
first find the factors and group them all together, delete any repeats
6=2*3
8=2*2*2
least common multiple=2*2*2*3=24
so 6 bags=2.46
multiply by 4 to get 24
24 bags=9.84
so 8 bags=3.20
multply by 3
24 bags=9.60
9.84>9.60 so
the 8 ounce bag is less expensive
A = 1
4/17=2/8.5
