Answer:
Number of blades of grass on a football field.
Number of Pages in the novel.
Number of members in your immediate family.
Number of musicians.

¯\_(ツ)_/¯
First, find a common denominator (the bottom number) Then add the tops as usual. Four and five have a common denominator of 20 so: 8/20+5/20=13/20
What this doesnt make sense
Negative exponents mean that you flip the number upside down
so -7^-2 would become 1/-7^2
-7^2 would be 49
so the answer is <em>1/49</em>
