Scale Factor of 2 and 1

What is the Scale Factor of 2 and 1? What is the Scale Factor between 2 and 1? More specifically, what is the Scale Factor from a length of 2 to a length of 1? In other words, what (Scale Factor) can you multiply by 2 to get 1 as illustrated below?:

2 × Scale Factor = 1

To solve the equation above, you simply divide both sides by 2 to get the Scale Factor alone on the left side:

(2 × Scale Factor)/2 = 1/2
Scale Factor = 1/2

We could leave the answer like that, but we have also converted the answer to its simplest fraction form and to decimal form:

Fraction answer = 1/2
Decimal answer = 0.5

You may also be interested to know that we verified that 2 × 1/2 = 1 is true, which means that our answer is correct. Also, note that since 2 is greater than 1, this is a Reduction Scale Factor.
