Practical Applications
## How Maps Use Proportions
Maps use scale to show real distances. A map scale of 1 inch = 5 miles means every inch on the map stands for 5 miles in real life.
## Building Models
Proportions help you make models of cars, buildings, or even planets! Everything is reduced or enlarged by the same amount so it looks right.
## Why It Matters
Understanding proportions makes it easier to read maps, build models, and plan trips.
Examples
- A map shows your house and school are 2 inches apart. If the scale is 1 inch = 3 miles, they are 6 miles apart.
- A toy car is made at a 1:16 scale. If the real car is 16 feet long, the model is 1 foot long.
