Description

"Application of Scale" Scale PPT

Part One: Review the past and learn the new

Can anyone tell me what a scale is?

The ratio of the distance on the picture to the actual distance in a picture is called the scale of the picture.

Distance on the map/actual distance = scale

Application of scale PPT, part 2: exploration of new knowledge

Let’s talk about the specific meaning of each scale below.

(1) Scale 1:4500000

Indicates that a distance of 1 cm on the map represents an actual distance of 4,500,000 cm.

(2) Scale 80:1

It means that the distance on the picture is 80 centimeters, which means the actual distance is 1 centimeter.

(3) Scale

Indicates that a distance of 1 centimeter on the map represents an actual distance of 50 kilometers.

Think about it: What calculation methods do you have, talk to your peers.

Application of scale PPT, Part 3: Classroom exercises

On a map with a scale of 1:5000000, the distance from Shanghai to Hangzhou is measured to be 4.3 centimeters. How many kilometers is the actual distance from Shanghai to Hangzhou?

Solution: Assume the actual distance is x cm.

4.3: x = 1:5000000

x=21500000

21500000cm=215km

Answer: The actual distance from Shanghai to Hangzhou is 215km.

Application of scale PPT, Part 4 content: Class summary

How to find actual distance using scale:

Distance on the map/actual distance = scale

Actual distance = distance on the map ÷ scale

Distance on the picture ÷ actual distance = scale bar
