Question

The width of a picture is 20 cm. Using a color copier, you reduce the width of the picture to 5 cm. What is the scale factor of the dilation?
A. 5
B. 1/5
C. 4
D. 1/4
​

Answer 1

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Given- Width of the picture=20 cm

picture width reduces to 5 cm

scale factor =$\frac{5}{20}$=$\frac{1}{4}$

Scale factor of dilation=$\frac{1}{4}$

Answer 2

The answer is d (1/4)


because the original width of the picture is 20, then you reduce the width to 5.

so the scale factor of the expansion is 5/20 = 1/4

so therefore the answer is d.

i hope this helped u and good luck!
