Question

Elena’s bedroom door is 1.2 m wide. How wide should the door be on the scale drawing? Explain how you know.

Answer 1

0.016cm

Explanation:

I would convert 2cm in terms of meters

2cm/1 = 1m/100cm

since there are cm on top and bottom it cancels out

2•1 /1m• 100 = 2m/100 = .02 m

now you solve using proportions

x/.8 = .02/1

x= (.8)(.02) cross multiples)

x= 0.016
