Division expression:


(w)/(T)

where w represents the weight of the steel structure and T represents the total weight of the bridge's materials.

From the information given, we know that w = 400 tons. However, to get T we have to add all the materials as follows:


T=1000+400+200=1600

Then, T = 1600tons.

Finally, we replace the values to get a division expression:


(400)/(1600)

Simplifying the fraction we get:


=(4)/(16)=(1)/(4)

Answer:


(400)/(1600)=(1)/(4)
