$\bf \begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
\\\\
&&y=\cfrac{{{ k}}}{x}&\impliedby 
\begin{array}{llll}
k=\textit{constant}\\
\qquad \textit{of variation}
\end{array}
\end{array}\\\\
-----------------------------\\\\
$

$\bf y=\cfrac{k}{x}\qquad 
\begin{cases}
y=0.2\\
x=0.3
\end{cases}\implies 0.2=\cfrac{k}{0.3}\implies 0.2\cdot 0.3=k
\\\\\\
\textit{thus, the equation will be}\quad y=\cfrac{0.06}{x}$
