Answer:
For a fraction;
If the top number is bigger than the bottom number, that means it's greater than 1
If the top number is less than the bottom number, that means it's less than 1
If the top and bottom number is the same, that means it equals 1
In this problem we have 5/4. The top is bigger, so 5/4 is greater than 1.
Since we're multiplying 7 by a number greater than one, then the result will be greater than 7, also known as >
Which means answer choice C is correct for the second question because 5/4 is greater than 1
