0.0045

Step-by-step explanation:

$0.45\times 0.01$

Multiply without the decimal points, then put the decimal point in the answer

$45\times \:1=45\\\\\begin{matrix}\space\space&4&5\\ \times \:&\space\space&1\end{matrix}\\\mathrm{Mutliply\:the\:bold\:numbers}:\quad \:5\times \:1=5\\\frac{\begin{matrix}\space\space&4&\textbf{5}\\ \times \:&\space\space&\textbf{1}\end{matrix}}{\begin{matrix}\space\space&\space\space&5\end{matrix}}\\\\\mathrm{Mutliply\:the\:bold\:numbers}:\quad \:4\times \:1=4\\\frac{\begin{matrix}\space\space&\textbf{4}&5\\ \times \:&\space\space&\textbf{1}\end{matrix}}{\begin{matrix}\space\space&4&5\end{matrix}}$

$0.45\mathrm{\:has\:}2\mathrm{\:decimal\:places}\\0.01\mathrm{\:has\:}2\mathrm{\:decimal\:places}\\\\\mathrm{Therefore,\:the\:answer\:has\:}4\mathrm{\:decimal\:places}\\\\=0.0045$
