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.

At 12 noon in anchorage Alaska Janice noticed that the temperature outside was 12

Alisiya [41]

I assume that you want to know the temperature at a certain timing.
Well, you know that at 12:00 pm, the temperature was 12 F and that it decreases by a steady rate of 2 F each hour.

This means that at 1:00 pm, the temperature was 12-2 = 10 F
At 2:00 pm, the temperature was 10-2 = 8 F
At 3:00 pm, it was 8-2 = 6 F
.......and so on

You can follow this sequence to the timing you are looking for.
