The meaning of the drawing scale

The video tutorial explains the concept of scale, which is used in various fields. It covers two main cases: when the scale is less than 1, used for representing large distances in a minimized form, such as in maps, and when the scale is more than 1, used for enlarging small objects, like germs, to make them visible. Examples are provided for both cases to illustrate the application of scale in real-world scenarios.

What is the primary purpose of using a drawing scale less than 1?

• To enlarge small objects

• To reduce large real distances

• To increase the real length

• To maintain the same size

In the example given, what is the ratio of drawing length to real length?

• 3 kilometers to 250 centimeters

• 3 centimeters to 250 kilometers

• 3 meters to 250 kilometers

• 3 centimeters to 250 meters

What happens when the drawing scale is more than 1?

• Small objects appear smaller

• Large objects appear smaller

• Large objects appear larger

• Small objects appear larger

Why do we use a drawing scale more than 1 for germs?

• To maintain their actual size

• To make them invisible

• To see them without a microscope

• To reduce their size

Which of the following is NOT a use of drawing scales?

• Drawing maps

• Increasing the real size of objects

• Enlarging microscopic objects

• Reducing large distances
