Answer:
17/15
Step-by-step explanation:
Find the GCF of the denominators
15
Convert the fractions
1/3 ---> 5/15
4/5 ---> 12/15
Add.
12/15 + 5/15 = 17/15
1. If the product of these integers is to be 1, then all of them must be either 1 or -1.
2. Since the product is positive (+1), it must be that there are an *even* number of negative ones (-1), if any.
3. If the sum were 0 it would mean that the number of +1's must equal the number of -1's. So that means there would have to be exactly 22/2=11 of each.
4. But if there were 11 of each, that means the number of -1's would be *odd* and there's no way the product could be +1 (as stated in 2 above).
Hence, the sum is never 0, if the product of 22 integers is equal +1.
The answer is C (3rd answer choice) O {-8,8}.
