What is the scaling factor if a picture goes from 3.5 inches on one side to 1inch on the same side?

To determine the scaling factor, we divide the final size by the original size.

Scaling factor = Final Size / Original Size

In this case, the final size is 1 inch and the original size is 3.5 inches.

Scaling factor = 1 inch / 3.5 inches

= 0.2857 (rounded to 4 decimal places)

Therefore, the scaling factor is approximately 0.2857 when a picture goes from 3.5 inches on one side to 1 inch on the same side.
