True

Step-by-step explanation:

Say u had a question like this

"Maddy went to get 5 things from the store.When she got back she bought 10 more items . how many more items were bought

u would set it up like:

5                x

_=            _

10               100

Times 100 and 5 and divide by 10

tube or goog would be a great resource to with that question

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
