Chapter 2: Q5. (page 114)

Solve each proportion. If necessary, round to nearest hundredth.
$\frac{4}{u} = \frac{28}{35}$

Short Answer

Expert verified

The value of $u = 5$ .

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:

$\begin{matrix} \frac{4}{u} = \frac{28}{35} \\ 4 (35) = (28) u \end{matrix}$

Step-3. Simplify for u.

To further simplify, divide each side by 28.

$\begin{matrix} 4 (35) = (28) u \\ 140 = 28 u \\ \frac{140}{28} = \frac{28 u}{28} \\ 5 = u \end{matrix}$

Therefore, the value of $u = 5$ .
