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

\\(\frac{10}{3} \div 25 = 2 \div 15\\)

Explanation:

Write the given ratios as fractions

$$ \frac{10}{3} \quad \text{and} \quad \frac{2}{15} $$

Apply the cross product property

$$ 10 \times 15 = 150 $$

$$ 3 \times 2 = 6 $$

Compare the cross products

$$ 150 eq 6 $$
