On the blueprint of a house, 33 millimeters represents 8 meters. The actual length of the living room is 6 meters. What is its length on the blueprint?

Question

what is the length of the blueprint?

Answer 1

What we have is a ratio problem:

^{33 mm} / _{8 m} = ^x / _{6 m}

Multiply both sides by 6 meters:

^{33 mm * 6 m} / _{8 m} = x

You can factor/cancel out a 2 and the meters:

^{33 mm * 3} / ₄ = x

Complete that, and you'll have your final answer.

Answer 2

33/8 = 6/b

 

Cross multiply and solve for b.
