      "full_response": "To solve this problem, we need to determine the number of robes that can be made given the constraints on both fabric and trim.\n\nStep 1: Calculate the amount of fabric needed for one robe.\n- A single robe requires \\(2 \\frac{1}{2}\\) yards of fabric. Converting this mixed number to an improper fraction:\n\\[ 2 \\frac{1}{2} = \\frac{5}{2} \\text{ yards} \\]\n\nStep 2: Calculate the amount of trim needed for one robe.\n- A single robe requires \\( \\frac{1}{8} \\) yard of trim.\n\nStep 3: Determine how many robes can be made with the available fabric.\n- We have 10 yards of fabric. To find out how many robes we can make, divide the total amount of fabric by the amount needed per robe:\n\\[ \\text{Number of robes from fabric} = \\frac{10}{\\frac{5}{2}} = 10 \\times \\frac{2}{5} = 4 \\]\n\nStep 4: Determine how many robes can be made with the available trim.\n- We have 1 yard of trim.

Here, fabric limits us to 4 robes.\n\nTherefore, the final answer is:\n\\boxed{4}",
