Answer:

All statements are true

Step-by-step explanation:

1. The statement S_{500}>S_{499} is true, because S_{499} is the sum of first 499 terms,  S_{500} is the sum of first 500 terms,  and all these terms are positive, then the sum of smaller number of terms is less than the sum of larger number of terms.

2. The statement S_{500}>a_{500} is true, because S_{500} is the sum of first 500 terms,  a_{500} is 500th term and the sum of 500 terms is greater than the 500th term.

3. The statement S_1=a_1 is true, because S_1 is the sum of first 1 term that is exactly  a_1.

All statements are true.

1 + (-5/8) = 3/8

Explanation: If the coffee wasn’t drank it would’ve been at fraction 1 (or 100%)

Since he drank 5/8 of it. The coffee left is now 1-(5/8)

But since the question has asked to give the equation in addition format. Put a plus sign in between the two.

Therefore,
1 + (-5/8)

Solve it,
= 1-(5/8)
= (8-5)/8
= 3/8

Hence the equation is:

1 + (-5/8) = 3/8.
