The scale factor between two similar shapes is the ratio of the dimensions of one (often the smaller) compared with the dimension of the other (the larger).
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.

If you know one of the sides of both the rectangles than you just divide them by one another to find the scale factor.
The two scale factors are reciprocals of one another.
To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.

Assuming the smaller sphere is the image of the larger sphere after transformation (based on the order of the radii): the scale factor is 4/12 = 1/3
100 is the scale factor

Scale Factor
Yes, a scale shows measurements of a smaller distance that proportionately represents a larger distance. By using a consistent ratio or scale factor, the smaller distance displayed on the scale can accurately convey the larger distance being measured.
Finding the scale factor for two polygons is simple to do. All you have to do is find the angles in a rectangle.
