How do you find the scale factor model?

all you have to do is have to figure out from which of the shapes your starting with. So if you decide to start with a scale factor from the larger figure to the smaller figure all u do is the opposite. You do the small divided my the large. So if u want it from the small shape to the large shape scale factor you do the large divided by the small.

A transformation that proportionally reduces or enlarges a figure?

Scaling will proportionally reduce or enlarge a figure. The amount of scaling is given by the scale factor (greater than zero) If the scale factor is less than 1, the figure is reduced and it is sometimes called a contraction If the scale factor is greater than 1, the figure is enlarged, and it is called a dilation or enlargement. If a centre of enlargement is used, the distance of every point from the centre is multiplied by the scale factor. The scale factor can be negative in which case the distance to the new point is measured on the opposite side of the centre to the original point.

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.
