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

`(1)/(4)`

Explanation:

Given- Width of the picture=20 cm

picture width reduces to 5 cm

scale factor =
`(5)/(20)`=
`(1)/(4)`

Scale factor of dilation=
`(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!
