Reggie is making doll clothes for his little sister. He has 3 yards of fabric. If each dress uses 3/8 yard of fabric, how many dresses can he make?(

To determine the number of dresses Reggie can make, divide the total amount of fabric by the amount used per dress: 3 yards / 3/8 yard/dress = 3 / (3/8) = 3 * (8/3) = 24/3 = <<3*(8/3)=8>>8 dresses. Answer: \boxed{8}.
