A dilation is a transformation (notation) that produces an image that is the same shape as the original, but is a different size.
This uses the concept of proportions.
.002 converted to a fraction is 2/1000, or 1/500.
We set up the proportion like so:
10/100 = .002/x
Solve for x.
Cross-multiply.
10 * x = .002 * 100
10 * x = .2
x = .2 / 10
x = .02
The answer is .02
