Answer :
If the scale factor is more than 1, it is an enlargement, if it is less than 1, it is a reduction.
3.5 = enlargement
2/5 = reduction
0.6 = reduction
14.1 = enlargement
4/3 = enlargement
5/8 = reduction
For the next question,
Just divide the x-values(or y-values) of any points of the original to the new one.
4.5 / 3 = 1.5
So the scale factor is 1.5.
