megahertz has the symbol MHz, where M stands for "mega" and Hz for "hertz".
The number given is 11467 kHz, and k stands for kilo.
These prefixes can be rewritten as a power of 10:
[tex]\begin{gathered} k=10^3 \\ M=10^6 \end{gathered}[/tex]So, we can see that:
[tex]\begin{gathered} \frac{k}{M}=\frac{10^3}{10^6} \\ \frac{k}{M}=10^{-3} \\ k=10^{-3}M \end{gathered}[/tex]So, we can input that into the place of k:
[tex]11467kHz=11467\times10^{-3}MHz=11.467MHz[/tex]So, 11467 kHz is the same as 11.467 MHz.
