Answer 1

`\\ \text{Given that a 12-foot section of a beam weighs p pounds}.\\ \text{and we need to find the weight of a 5-foot section of the beam.}\\ \\ \text{to find the weight, we use the proportion.}\\ \\ \text{Since weight of 12-foot section of beam is p pounds, }\\ \text{so weight of 1-foot section of the beam is}=(p)/(12) \text{ pounds}\\ \\ \text{and hence weight of 5-foot section of beam is}=(5p)/(12) \text{ pounds}`

Weight of 5-foot section of beam is: (5p/ 12) pounds.
