Question

A 36 inch by 48 inch poster is reduced to an image that is 3 in by 4 inch in size. What is the scale factor?

A: 1/3
B: 1/6
C: 1/9
D: 1/12

Answer 1

The correct answer for the question that is being presented above is this one: "D: 1/12."
The original dimension is 36 x 48.
The scaled dimension is 3 x 4.

The ration between 3 and 36 ; 4 and 48 is reduced to 1/12.
So the scale factor is 1/12.
