1 shape cannot have a scale factor. A scale factor is something (a factor) that relates one shape to another.
A scale Factor is Algbrea so you have to... x - + and/or divided.
A scale factor is a number which scales, or multiplies, some quantity. A scale factor of two would mean to multiply whatever it is by two.
4 to 1

No, 16 is a multiple of 4. 4 is a factor of 16.
1 to 30
Since the scale factor of the moon to the earth is 1:4, then the ratio of their areas will be the scale factor squared or 1:16. The ratio of their volumes will be the scale factor cubed or 1:64.
1.25
Yes.
it is 4 since 4 is a factor of 16 and there can be no bigger factor of 4 than 4 itself.
56/4 = 14
The area is directly proportional to the square of the scale factor. If the scale factor is 2, the area is 4-fold If the scale factor is 3, the area is 9-fold If the scale factor is 1000, the area is 1,000,000-fold
Factor pairs of 16 are 1 and 16, 2 and 8, and 4 and 4.
Assuming the smaller sphere is the image of the larger sphere after transformation (based on the order of the radii): the scale factor is 4/12 = 1/3
