Short Answer

Expert verified

The value of $w = 1.32$ .

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:

$\begin{matrix} \frac{w}{2} = \frac{4.5}{6.8} \\ 6.8 (w) = (4.5) 2 \end{matrix}$

Step-3. Simplify for w.

To further simplify, divide each side by 6.8.

$6.8 (w) = (4.5) 2 6.8 w = 9 \frac{6.8 w}{6.8} = \frac{9}{6.8} w = 1.32$

Therefore, the value of $w = 1.32$ .
