Makhi Mills · Answer 1

Answer: the correct is answer is: c

Jaylin Mcpherson · Answer 2

The answer is C, 1,2 and 7,14. I know this because 1/2 is the same at 7/14. 7 is exactly half of 14, so if I divide 7/14 by 7 I get 1/2 which is our other set. Therefore, since we know the ratio is equivalent, it is proportional.
