Question

Hi, I'm new here and I need help with this math problem
What is the scale factor for the similar figures?

A. 4
B. 3/2
C. 2/3
D. 1/4

Answer 1

notice how the "8 cm" corresponds to the "2 cm"

you divide the two (new/old) to get 2/8 = 1/4

essentially you multiply EVERY dimension of the old figure by 1/4 to get the new dimensions

Answer 2

you can also use the 12 and 3

new/old = 3/12 = 1/4

and you get the same answer

Answer 3

@jim_thompson5910 can you go through that slowly

Answer 4

where are you stuck?

Answer 5

I didn't get it when you said to multiply every dimension by 1/4

Answer 6

if you multiplied 12 by 1/4, you would get 3

1/4 = 0.25

so if you multiplied 12 by 0.25, you get 3

Answer 7

multiply 8 by 0.25 and you get 2

Answer 8

Oh, ok. I get it. Thank you! :)

Answer 9

you're welcome
