Question

Each floor of a building is 12.4 feet tall. If the height of the building is 99.2 feet how many floors does the building have?

Answer 1

We know that: 

each floor is 12.4 feet tall

the whole building is 99.2 feet tall

 

We are trying to find out how many floors are in the building. 

 

The equation would be 

the height of one floor * the number of floors = the total height of the building 

 

12.4*x=99.2

 

Divide (99.2/12.4) to find x

x=8 

 

So there are 8 floors all together in the building. 

 

CHECK: 12.4 ft * 8 floors = 99.2 ft
