Because the triangles are similar triangles, they must have proportional corresponding sides. This means that we must have
[tex]\frac{UW}{KM}=\frac{UV}{KL}=\frac{VW}{LM}[/tex]
Seeing your figure, suppose the largest side is [tex]LM[/tex], so we have
[tex]LM=24[/tex]
Then, for you to obtain the desaired quotiens, you mus let
[tex]VW=16; KM=19.5; UW=13; KL=6; UV=4[/tex]
And so we have
[tex]\frac{13}{19.5}=\frac{4}{6}=\frac{16}{24}=0.66666...[/tex]
