Question

10. What is the scale factor if a 6" by 14" photograph is enlargedto a poster that is 2 ft. by 4.67 ft.?

Answer 1

The scale factor of the first side is from 6" to 2 ft so:

`6`

so the factor is:

`(2)/((1)/(2))=4`

now for the other side:

`14`

so the factor is:

`(4.67)/((7)/(6))=4`

So the scale factor is: 4
