Question

Does anyone know the answer to this

Answer 1

Hello!

We can write this as a proportion below.

$\frac{blueprint}{real} = \frac{0.5}{4} = \frac{18}{x}$

As you can see, 4 is eight times 0.5. Therefore, we can multiply eighteen by eight to get our answer.

18(8)=144

Just to check, we can cross multiply and divide.

72/0.5=144

Therefore, our answer is 144 feet.

I hope this helps!
