We can pose this proportion as follows:

[tex]\frac{76k}{2h}=\frac{38k}{x}\Rightarrow\frac{2h}{76k}=\frac{x}{38k}\Rightarrow x=\frac{2h\cdot38k}{76k_{}}=\frac{2h\cdot1}{2}\Rightarrow x=1h[/tex]

Therefore, the answer to this value is x = 1 h.

We can check as follows:

[tex]\frac{76}{2}=\frac{38}{1}=38[/tex]

The ratio is constant (38).
