** Use equivalent ratios to solve the proportion.**

**$\frac{2}{7}=\frac{x}{21}\text{\hspace{0.33em}}$**

The solution is ** x = 6**.

The given proportion is $\frac{2}{7}=\frac{x}{21}$.

We have to solve the proportion by using equivalent ratios.

Solve the given equation.

$\begin{array}{c}\frac{2}{7}=\frac{x}{21}\\ \frac{2}{7\times 3}=\frac{x}{21}\text{}\left[\text{compare denominators}\right]\\ \frac{2\times 3}{21}=\frac{x}{21}\text{\hspace{0.33em}}\left[\text{find}x\right]\\ x=2\times 3\\ x=6\end{array}$

So, the solution is ** x = 6**.
