Answer 1

Do you know how to use ratios or proportions?

Answer 2

you would use a ratio or a proportion for this one. The scale from the blueprint to house is 36mm to 7m, does that ring a bell? Remember you can write a ratio in 3 different way. That is one of the ways.

Answer 3

So you would use it as a ratio- 36 is to 7 (or 36:7) as 27 is to x (or 22:x) and now you can find x by cross-multiplying and dividing. Good Luck!

Answer 4

Use ratios eg 36mm=7000mm to find 27mm
