Explanation of Solution

Given:

The given equation is $\frac{3}{7}=\frac{\boxed{}}{21}$ .

Calculation:

Consider the given equation is,

  $\frac{3}{7}=\frac{\boxed{}}{21}$

Solve for the missing term as,

  $\begin{array}{l}\frac{3}{7}=\frac{x}{21}\\ x=\frac{3}{7}\left(21\right)\\ x=\left(3\right)\left(3\right)\\ x=9\end{array}$

Then, the complete statement is,

  $\frac{3}{7}=\frac{9}{21}$
