Hello there!

So first, yes, you find the missing length (piece plus piece equals whole part) and proportional, you just visualize ( like let's say there are two similar shapes  that are smilier : ABCD~ FGHJ  and let's say AB is 3   FG is 9 , so i would say 3/9 . And for CD is ,..let's say 8 and HJ is 16, so 8/16. So basically:


3  =  9
--      --
8       16         <--- that's how you set up proportional





i  hope you understand , and if not, feel free to message me! 

Have a beautiful day
