Answer:
3. enlargement
5. enlargement
6. reduction
Step-by-step explanation:
You want to know whether the given scale factors for dilation represent an enlargement or a reduction.
Dilation
A dilation is an enlargement if the scale factor is greater than 1. It is a reduction if the scale factor is less than 1.
3. k = 1.25
1.25 > 1, so this is an enlargement
5. k = 5/4
5/4 = 1.25, so this is the same problem as 3. It is an enlargement.
6. k = 0.85
0.85 < 1, so this is a reduction.
