Answer:
1 and 3 is the counter example.
Step-by-step explanation:
The sum of - 2.5 and - 8 is - 10.5 and their product is (- 2.5) × (- 8) = 20
Therefore, Sum is smaller than the product.
The sum of - 1 and - 3 is - 4 and their product is (- 1) × (- 3) = 3
Therefore, Sum is smaller than the product.
Again, the sum of 1 and 3 is 4 and their product is (1) × (3) = 3
Therefore, Sum is greater than the product.
Now, the sum of 2.5 and 8 is 10.5 and their product is (2.5) × (8) = 20
Therefore, Sum is smaller than the product.
Hence, 1 and 3 is the counterexample. (Answer)
