Scale (Масштаб)
Understanding how maps, drawings, and models represent real-world objects
1. What is Scale?
Scale is the ratio between a distance on a map or drawing and the corresponding real distance.
Key Idea:
Scale shows how many times a real object is reduced (made smaller) or enlarged (made bigger) in the drawing.
Example: A scale of 1:100 means:
- 1 cm on the drawing = 100 cm in reality
- The real object is 100 times larger than the drawing

2. Ways to Write Scale (Scale Notation)
Ratio Form
1:1000
Read as "one to one thousand"
Fraction Form
1⁄1000
As a mathematical fraction
Verbal Form
1 cm = 10 m
In words with units
All three forms express the same relationship!
1:1000 means the real object is reduced 1000 times in the drawing.
1:1000 means the real object is reduced 1000 times in the drawing.
