Scale Drawing

A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount is called the scale drawing.

.

 

For example: This drawing has a scale of "1:10", so anything drawn with the size of "1" would have a size of "10" in the real world, so a measurement of 1mm on the drawing would be 10mm on the real horse.
 
Example 1

Write the scale 1 cm to 1 m in ratio form.

Solution

1cm to 1m

= 1cm : 1m

= 1cm : 100cm

= 1 : 100

Example 2

Simplify the scale 5 mm: 1 m

Solution:

5mm : 1m

= 5mm : 100cm

= 5mm : 1000mm

= 5 : 1000

= 1 : 200
