One way to solve the exercise is to use the rule of three, like this


\begin{gathered} 8\text{ chairs}\rightarrow1\text{ table} \\ 16\text{ chairs}\rightarrow x\text{ tables} \end{gathered}
\begin{gathered} x=\frac{16\text{ chairs }\cdot\text{ 1 table}}{8\text{ chairs}} \\ x=(16)/(8)\text{ tables} \\ x=2\text{ tables} \end{gathered}

Therefore, the missing number to complete the proportion is 2.
