To evaluate the expression \(-144 / -12\):
- First, divide \(-144\) by \(-12\): \[ -144 / -12 = 12 \] (Note that dividing two negative numbers results in a positive number.)
Now, we will analyze the result, which is \(12\), according to the provided options:
a) Negative: This cannot be used to describe \(12\) since \(12\) is a positive number.
b) Rational number: \(12\) can be expressed as a fraction (\(12/1\)), so it is a rational number.
c) Integer: \(12\) is an integer.
d) Whole number: \(12\) is also a whole number (non-negative integer).
From the above analysis, the only option that cannot be used to describe \(12\) is:
a) Negative.
