Question

Choose the dilation that would represent a reduction

A. k=2
B. k=4/3
C. k=3/4
D. k=1.2

Answer 1

For this case, the first thing you should know is that there are two possible cases:

Case 1:
If 0 <k <1 then there is a reduction of the orignal figure.

Case 2:
If k> 1 then there is an expansion of the originial figure.

Therefore, in this case, the scale factor that represents a reduction is given by:
k = 3/4 = 0.75 (0 <k <1)

Answer:
the dilation that would represent a reduction is:
C. k = 3/4
