Not necessarily.
Most maps will have scales written with units. Map scales in the Imperial system are sometimes written as 2 inches = 1 mile, for example. This could be simplified to 1:31680. In the simplest form, this is 1 inch = 31680 inches but that would not be particularly meaningful to most users.
Similarly, in the metric system, scales may be written as 4 cm = 1 km rather than 1:25000. In the simplest form this is 1 cm = 25000 cm. Again, not particularly user friendly.
The ratio of the circumference of a circle to its diameter is a constant, irrespective of the actual measurements. This ratio is called pi and is 3.1415...
The constant of proportionality or scale factor.
Expressed as a ratio in its simplest terms, 105:150 is equal to 7:10, or seven to ten.
A ratio of 6:2 could be simplified to 3:1.
257:144

The scale gives the ratio that compares the measurements of the drawing or model to the measurements of the real object. Scale factor is a scale written as a ratio without units in simplest from.

scale drawing An example might be 4:1 This is a ratio in its simplest form (it cannot be further simplified mathematically) and it's expressed with no units (not in inches or milimeters etc).

if it is a ratio you do not put it in simplest form but here is the answer anyways 1/10.
