The percentage change can be found below


\begin{gathered} \text{percentage change = }\frac{\text{ new number}-\text{original number}}{\text{original number}}*100 \\ \text{percentage change=}(18-45)/(45)*100 \\ \text{percentage change}=-60 \\ \end{gathered}

Since the percentage is negative, this means there is a 60% decrease.
