To determine which ratio forms a proportion with 32:18, we need to check which of the given ratios is equal to 32:18. We can simplify each option and compare them directly.

Option A, 18:32

This is the reverse of 32:18 and cannot be simplified to match 32:18, so it is not proportional to 32:18.

Option B, 16:9

Simplify 16:9. Since there are no common factors other than 1, it remains 16:9. This is equal to 32:18 because 32:18 can simplify to 16:9, so 16:9 is proportional to 32:18.
