use the cross product property to determine whether or not the following equations are proportions:

\\(\frac{1}{4} \div 0.5 = \frac{1}{6} \div \frac{1}{3}\\)

Explanation:

Convert the ratios to fractional form

$$ \frac{1}{4} : 0.5 = \frac{1}{6} : \frac{1}{3} \implies \frac{\frac{1}{4}}{0.5} = \frac{\frac{1}{6}}{\frac{1}{3}} $$

Apply the cross product property

$$ \frac{1}{4} \cdot \frac{1}{3} = \frac{1}{12} $$

$$ 0.5 \cdot \frac{1}{6} = \frac{1}{2} \cdot \frac{1}{6} = \frac{1}{12} $$

Compare the cross products

$$ \frac{1}{12} = \frac{1}{12} $$

Answer:

Use the cross product property to determine whether or not the following equations are proportions:

\(\frac{1}{4} \div 0.5 = \frac{1}{6} \div \frac{1}{3}\)
