please help me i don’t understand how to get FG (10th grade math) thank you so much

Answer:
[tex]FG=2.8[/tex]
Step-by-step explanation:
FE corresponds with LM
FG corresponds with MN
So, we can make a ratio I will make x represent FG
[tex]\frac{4}{5} =\frac{x}{3.5}[/tex]
Cross multiply
[tex]5x=4(3.5)[/tex]
[tex]5x=14[/tex]
Divide both sides by 5
[tex]x=2.8[/tex]
I hope this helps
