To determine which ratio forms a proportion with 11:13, we need to check which of the given ratios is equal to 11:13. We can simplify each option and compare them directly.

Option A, 13:11

This is the reverse of 11:13 and cannot be simplified to match 11:13, so it is not proportional to 11:13.

Option B, 22:36

Simplify 6:4 by dividing both terms by 2:

22:36 = 11:18

22:36 simplifies to 11:18. This is not equal to 11:13, so it is not proportional to 11:13.
