8. What is x:y?
Think and write the answers in your notebook. You have 2 minutes.

9. x:y is a scale where
1 unit of length in real ≡ x/y units of length in drawing
For example, 1:100 is a scale where
1 unit of length in real ≡ 1/100 or 0.001 unit of length in drawing
If the unit of length is metre, then
1 m in real ≡ 0.001 m or 1 cm in drawing
