Design a factory building. Use a distance of 10 centimeters on the plan to represent a distance of 10 meters on the ground. Find the ratio of the distance on the picture to the actual distance.

To ask for the ratio of the distance on the picture to the actual distance, can we directly use the two sequence equations given in the question? Why? What should I do?

(1) The scale bar is different from the general ruler. It is a ratio and should not have a unit of measurement.

(2) When calculating the scale, the unit lengths of the front and back items must be converted into units of the same level.

(3) The first term of the scale should generally be simplified to "1".

Which of the following passages are scales and which are not? Why?
