$\bf g=18(0.5)^{\frac{x}{5}}
\\\\\\
\textit{how much is there after a year?}\qquad g=18(0.5)^{\frac{1}{5}}\implies g\approx 15.67$

so, it was initially 18grams, after 1year, x = 1, it went down to 15.67grams, for a difference of about 2.33 grams.

now, if we take 18 to be the 100%, how much is 2.33 in percentage off of it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
18&100\\
2.33&p
\end{array}\implies \cfrac{18}{2.33}=\cfrac{100}{p}\implies p=\cfrac{2.33\cdot 100}{18}$

round it up if you need to, that's the percentage differential.
