Final answer:
The scale factor is 1/4.
Step-by-step explanation:
The scale factor is 1/4.
The scale factor is the relationship between the scale dimension and the actual dimension. It is often written as a ratio, such as 1:4 or 1/4. In this case, a scale factor of 1/4 means that the scale dimension is 1/4 of the actual dimension. For example, if the scale dimension is 4, then the actual dimension would be 4 times 1/4, which is 1.
For example, if a drawing of a rectangle has a width of 2 inches and a similar rectangle has a width of 9 inches, the scale factor used to convert the larger rectangle to the smaller rectangle would be 1/4.
