To determine whether the ratios \( \frac{6}{11} \) and \( \frac{30}{55} \) form a proportion, we can cross-multiply and check if the products are equal.
Cross-multiplying gives us:
\[
6 \times 55 \quad \text{and} \quad 11 \times 30
\]
Calculating the products:
1. \( 6 \times 55 = 330 \)
2. \( 11 \times 30 = 330 \)
Since both products are equal (\( 330 = 330 \)), the ratios do form a proportion.
The answer is:
