Explanation:
It is given that: height of building is directly proportional to the number of floors.
It means if height increases , then number of floor increases, and vice versa.
Given:
- Height of building = 104 ft
- No. of floors = 8 floors
Ratio of h:f
Unit rate refers to, here, the ratio of no. of floors : height of building. It's similar to the the ratio with denominator as 1.
Hence for (b), unit rate: 13:1
This refers to each floor has height of 13 ft.(c)
