Fill in the blanks to expand the expression. \[ \begin{aligned} \frac{2}{7}(n+11) & =\left(\frac{2}{7}\right) \square+\left(\frac{2}{7}\right) \\ & =\end{aligned} \]

To expand the expression \(\frac{2}{7}(n+11)\), you would distribute \(\frac{2}{7}\) to both terms inside the parentheses. This means you multiply \(\frac{2}{7}\) by \(n\) and \(\frac{2}{7}\) by \(11\). So, you fill in the blanks like this: \[ \begin{aligned} \frac{2}{7}(n+11) & =\left(\frac{2}{7}\right) n + \left(\frac{2}{7}\right)(11) \\ & = \frac{2n}{7} + \frac{22}{7} \end{aligned} \]
