Answer:

  48/132

Step-by-step explanation:

The length of 1.5-inch screws is ...

  36 × 1.5 in = 54 in

The length of 2-inch screws is ...

  24 × 2 in = 48 in

The length of 2.5-inch screws is ...

  12 × 2.5 = 30 in

The total length of all screws is ...

  54 in + 48 in + 30 in = 132 in

Then the ratio of 2-in screw length to total screw length is ...

  2-in : total = 48 : 132
