Quad abcd ~ quad efgh, find the lengths of sides 1, 2, and 3. i am stuck on 1 and 3. number 2 is 8.25 and 1 is not 22. 3 is not 10.125. !

It looks like you need to flip the second figure to line it up with the first figure.  So the bottom right side has a ratio of 27:9 or 3:1

In other words the left figure is 3 times bigger than the right figure.  So my answers are:
 
1) 18, because it is 3 times bigger than 6.
2) 5 1/3 or 5.33, because 16/3 is 5 1/3.
3) 8, because 24 divided 3 is 8.

Unfortunately, I did not get 8.25 as my answer for 2).  Hopefully that is fine.
