scale factor is just the ratio between corresponding sides of a figure.  that scale factor from figure 1 to figure 2 is just the ratio between sides.  3/18 or 1/6,  or 6/1... just depending on if you are going bigger to smaller or smaller to bigger.

Answer:

The scale factor is equal to [tex]\frac{1}{6}[/tex]

Step-by-step explanation:

we know that

If two figures are similar then the ratio of its corresponding sides is called the scale factor

Let

z-----> the scale factor

x-----> the corresponding side of Figure 2

y-----> the corresponding side of Figure 1

so

[tex]z=\frac{x}{y}[/tex]

we have

[tex]x=3\ units[/tex]

[tex]y=18\ units[/tex]

substitute

[tex]z=\frac{3}{18}[/tex]

simplify

[tex]z=\frac{1}{6}[/tex]
