Question

The height of a building is proportional to the number of floors. Write the ratio of height of the building to the number of floors. Then, find the unit rate, and explain what it means in this situation. The ratio of height of the building to the number of floors is ____. The unit rate is ____. This means that each floor of the building is ____ ft high.

Answer 1

Ratio is: height/floor

Unit rate: ft

Each floor is height/(number of floors) ft high

Explanation:

Let the height of a building be h and it's unit will be in ft.

Let the number of floors be n without units.

So to calculate the height to floor ratio, we need to divide the height by the number of floors.

Example:

Building is 140 ft tall, and has 10 floors.

Let's calculate floor height (fh)

fh = h/f

fh = 140 ft / 10

fh = 14 ft
