Martin uses 3/5 yard of fabric to make 1 backpack. How many backpacks can Martin make if he has a total of 9 yards of fabric?(1 point)
backpacks
If Martin uses 3/5 yard of fabric to make 1 backpack, then he can make 1/(3/5) = 5/3 = 1 2/3 backpacks per yard of fabric.
If he has a total of 9 yards of fabric, then Martin can make 9 * (5/3) = 45/3 = 15 backpacks. Answer: \boxed{15}.
