To determine which ratio forms a proportion with 5:7, we need to check which of the given ratios is equal to 5:7. We can simplify each option and compare them directly.

Option A, 7:5

This is the reverse of 5:7 and cannot be simplified to match 5:7, so it is not proportional to 5:7.

Option B, 14:10

Simplify 14:10 by dividing both terms by 2:

14:10 = 7:5

14:10 simplifies to 7:5. This is not equal to 5:7, so it is no...
