Integers include the positive and negative whole numbers including zero. An integer cannot be a decimal or fractional part with it.

The set of integers is denoted by the numbers $...,-4,-3,-2,-1,0,1,2,3,4,...$

The value of the expression $\frac{-144}{-12}$is 12, because the quotient two similar sign numbers is always positive.

The value of the expression $\frac{36}{-3}$is –12, because the quotient two different sign numbers is always negative.

The value of the expression $2\left(-6\right)$ is –12, because the product of two opposite sign numbers is always negative.

The value of the expression $-3\left(4\right)$is –12, because the product of two opposite sign numbers is always negative.

Thus, the expression which has a value of 12 is $\frac{-144}{-12}$.

Hence option (f) is correct.
