Answer 1

 3.30677211066 rounded by the nearest hundred-thousand is equal to 3.30677

Answer 2

$\bf \stackrel{\textit{one hundred thousand}}{100,000}\qquad \qquad \qquad \qquad \stackrel{\textit{one hundred thousandth}}{0.\underline{00,000}}\\\\ -------------------------------\\\\ 3.\underline{30677}211066\implies 3.30677$
