Answer:
1/4
Step-by-step explanation:
7/12 X 3/7 = 21/84 = 1/4
12000000 bytes is one frame, then you multiply that by 24 to get one second (288000000 bytes). Then I just multiplied that by 60 to get one minute (17.28 billion). After that I multiplied by sixty to get 1037000000000000 (1.037 trillion) so its 1.037 trillion bytes.
This is applying the formula

We have a slight problem, though, because we are measuring rate in miles per hour, and we are measuring time in minutes. To make this problem solvable, we need to convert to either miles per minute or convert the time to hours. I'm going to convert the 15 minutes into hours:

Now that all of the units match, we have:

You can finish from there I'm sure.
