Answer
Drawing an object involves using the ratio between homogeneous quantities. The ratio between a reduced segment and the original segment is called magnification ratio. The magnification ratio can take on any value. The dimensions of an object in a scaled representation vary proportionally to the scale factor. The scale factor is the ratio between the distance on the drawing and the corresponding distance on the object. The scale is indicated by a ratio, and if the value is less than 1, it is a reduction scale, while if it is greater than 1, it is an enlargement scale.
