Answer: the first equation is the answer.

Step-by-step explanation: As you can see the first equation is 5/7=15/21. The are proportional because 5*3=15 and 7*3=21. If they are multiplied or divided by the same number, then they are proportional. It does not work with adding, subtracting or flipping.
