To determine

Tosolve the proportion by using algebra.

Answer to Problem 5C

The solution of the given proportion is $x=10$ .

Explanation of Solution

Given information : the proportion given as,

  $\frac{2}{5}=\frac{x}{25}$

Calculation : the given proportion can be calculated as,

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

Therefore,

The solution of the given proportion is $x=10$ .
