Final answer:
To determine if a/b is equal to an integer, we need to consider the value of b. The correct answer is D) b = 1 or -1.
Step-by-step explanation:
To determine if a/b is equal to an integer, we need to consider the value of b. The given options are: A) b=0, B) b< 1, C) b> 1, D) b= 1 or -1. So, let's go through each option:
- If b = 0, then a/b is undefined because we cannot divide by zero.
- If b < 1, then a/b will result in a fraction, not an integer.
- If b > 1, then a/b will result in a fraction, not an integer.
- If b = 1 or b = -1, then a/b will always be an integer, regardless of the value of a (as long as a is also an integer).
Therefore, the correct answer is D) b = 1 or -1.
