A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount is called the scale drawing.
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
Solution:
1 cm to q m
= 1 cm : 1 m
= 1 cm : 100 cm
= 1 : 100
Solution:
5 mm : 1 m
= 5 mm : 100 cm
= 5 mm : 1000 mm
= 5 : 1000
= 1: 200
Solution:
5 cm : 2 km
= 5 cm : 2 km
= 5 cm : 200000 cm
= 1 : 4000
