** Use algebra to solve the proportion.**

**$\frac{2}{5}=\frac{x}{25}$**

The solution is $x=10$.

The given proportion is $\frac{2}{5}=\frac{x}{25}$.

We have to solve the proportion by using algebra.

Solve the given proportion.

$\begin{array}{c}\frac{2}{5}=\frac{x}{25}\\ \frac{2}{5}\cdot 25=\frac{x}{25}\cdot 25\text{}\left[\text{multiply each side by 25}\right]\\ \frac{50}{5}=x\text{\hspace{0.33em}}\left[\text{simplify}\right]\\ x=10\text{}\left[\text{divide}\right]\end{array}$

So, the solution is $x=10$.
