A house is, 24 millimeters represents 5 meters. The length of the living room is 30 millimeters on the blueprint. What is the actual length of the living room?

Question

Algebra 1A. Sophomore. I need this done very quickly.

Answer 1

Let me help you solve this proportion.

If 24 mm = 5 m

Then 1 mm = 5/24 m

So 30 mm = (30 × 5/24) m = 6.25 m

The actual length of the living room is 6.25 meters.

Answer 2

So i believe you would just set up a proportion. You don't have to worry about converting units.

 

So,

 

24/5 = 30/x

 

Solve for x.

 

24x=150

x=6.25 m

 

Does this seem right?
