<u><em>The correct answer is: </em></u>green and blue.
<u><em>Explanation</em></u><span>
<u><em>: </em></u>We want to see which fractions </span></span>
is a multiple of. We know that
is a multiple of
, because
*3=
.
We can divide fractions to determine if
is a multiple of
:
;
in order to divide fractions, flip the second one and multiply:
)*
=
=1
.
This did not divide evenly, so
is not a multiple of 1/2.
Checking to see if
is a multiple of
,
;
flip the second one and multiply:
*
=
=6.
This divided evenly, so
is a multiple of
.
For this case, what we must do is find the scale factor.
We have then that the scale factor is given by:
Where,
L1: side length of polygon ABCD
L2: side length of polygon PQRS
Note: both sides belong to the same side of each polygon
Substituting the values we have:
Rewriting we have:
Answer:
The scale factor of dilation is given by:
Is this from k12? i am a k12 student, and the answer should be 2.2 units but I could be wrong.
