Step-by-step explanation:

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
