Scale Factor of 4 and 12 What is the Scale Factor of 4 and 12? What is the Scale Factor between 4 and 12? More specifically, what is the Scale Factor from a length of 4 to a length of 12? In other words, what (Scale Factor) can you multiply by 4 to get 12 as illustrated below?:

4 × Scale Factor = 12

To solve the equation above, you simply divide both sides by 4 to get the Scale Factor alone on the left side:

(4 × Scale Factor)/4 = 12/4
Scale Factor = 12/4

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