To find three numbers that when added together equal zero using the given numbers (1, 3, 5, 7, 9, 11, 12, 15), we can use a combination of positive and negative numbers.

Let's go through the options:

Given numbers: 1, 3, 5, 7, 9, 11, 12, 15

1. Start by selecting a negative number. Since we need three numbers to sum to zero and have an odd number of options, it is best to choose a negative number that cancels out a positive number. In this case, let's choose -12.
Equation: -12 + ?

2. Now, we need two more numbers that sum to 12 to cancel out the negative 12. We can choose any combination of the remaining numbers, as long as the sum equals 12. Let's choose 1 and 11.
Equation: -12 + 1 + 11

3. Check if the sum equals zero:
-12 + 1 + 11 = 0

By choosing -12, 1, and 11, we can satisfy the equation Number + Number + Number = 0 using the given numbers.

Please note that this is only one possible solution. There may be other combinations of three numbers that sum to zero using the given numbers.
