Calculation:

In order to solve the given equation$\frac{r}{8}=\frac{25}{40}$ for the variable, isolate the variable term r on one side by performing some basic algebraic operations to get rid of the other numbers and terms associated with it.

Here to isolate r on both side, first multiply both sides by 8 and then multiply both sides by 40 and then simplify further as shown below,

$\frac{r}{8}=\frac{25}{40}$

$\frac{r}{8}\cdot 8=\frac{25}{40}\cdot 8$

$r=\frac{200}{40}$

$r=5$

Thus, the solution of the proportion is$r=5$ .

Step 1

$\frac{r}{8}=\frac{25}{40}$

Multiply both sides of the equation by 40, the least common multiple of 8, 40.

$5r=25$

Divide both sides by 5.

$r=\frac{25}{5}$

Divide 25 by 5 to get 5.

$r=5$

Multiply both sides of the equation by 40, the least common multiple of 8, 40.

Divide both sides by 5.

Divide 25 by 5 to get 5.
