Answer 1

@Michele_Laino

Answer 2

make a proportion

Answer 3

I need the answer

Answer 4

\[\frac{ JKL }{ MNO }\frac{ 3 }{ 2 }=\frac{ KL }{ 5 }\]cross-multiply and solve for x

Answer 5

oh KL is x lol

Answer 6

as @AriPotta has well said, we have to write a proportion, namely:
\[3:2=KL:5\]
so \[2*KL=15\]

Answer 7

holy sh*t that is very complicated

Answer 8

and:
\[KL=\frac{ 15 }{ 2 }\]

Answer 9
