Final answer:
The result of 3 multiplied by 5 is 15, and one half multiplied by 0 is 0, because any number multiplied by 0 results in 0.
Step-by-step explanation:
The question asks about the result of two multiplication operations.
Specifically, it asks what is 3 multiplied by 5 and what is one half multiplied by 0.
For the first part, 3 multiplied by 5 is 15.
For the second part, when any number is multiplied by 0, the result is always 0.
This is because the multiplication property states that zero times any number equals zero.
Hence, the result of one half multiplied by 0 is 0.
