Chapter 2: Q6. (page 114)

Solve each proportion. If necessary, round to nearest hundredth.
$\frac{3}{8} = \frac{b}{10}$

Short Answer

Expert verified

The value of $b = 3.75$ .

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:

$\begin{matrix} \frac{3}{8} = \frac{b}{10} \\ 10 (3) = (b) 8 \end{matrix}$

Step-3. Simplify for b.

To further simplify, divide each side by 8.

$10 (3) = (b) 8 30 = 8 b \frac{30}{8} = \frac{8 b}{8} 3.75 = b$

Therefore, the value of $b = 3.75$ .
