Chapter 2: Q20. (page 115)

Solve each proportion. If necessary, round to nearest hundredth.
$\frac{8}{13} = \frac{v}{21}$

Short Answer

Expert verified

The value of $v = 12.92$ .

Step by step solution

Step-1. Define equivalent ratios.

Equivalent ratios are two ratios which have same relationship between the numbers.

Step-2. Find the cross products.

The given ratios can be simplified by doing cross product:

$\begin{matrix} \frac{8}{13} = \frac{v}{21} \\ 21 (8) = (v) 13 \end{matrix}$

Step-3. Simplify for v.

To further simplify, divide each side by 13.

$\begin{matrix} 21 (8) = (v) 13 \\ 168 = 13 v \\ \frac{168}{13} = \frac{13 v}{13} \\ v = 12.92 \end{matrix}$

Therefore, the value of $v = 12.92$ .
