Question

Which of the following does not represent an integer? (a) $0÷\left(-7\right)$ (b) $20÷\left(-4\right)$ (c) $\left(-9\right)÷3$ (d) $\left(-12\right)÷5$

• A. (a)
• B. (b)
• C. (c )
• D. (d)

Answer 1

The correct option is D

(d)

Explanation for the correct option:

Option (d): Consider $\left(-12\right)÷5$.

$\left(-12\right)÷5=-2.4$

$\left(-12\right)÷5$ does not represent the integer since the value of $\left(-12\right)÷5$ is in decimal.

Hence, option (d) is correct.

Explanation for the incorrect options:

Option (a): Consider $0÷\left(-7\right)$.

$0÷\left(-7\right)=0$

$0÷\left(-7\right)$ represents the integer since the value of $0÷\left(-7\right)$ is not in decimal.

Therefore, option (a) is incorrect.

Option (b): Consider $20÷\left(-4\right)$.

$20÷\left(-4\right)=-5$

$20÷\left(-4\right)$ represents the integer since the value of $20÷\left(-4\right)$ is not in decimal.

Therefore, option (b) is incorrect.

Option (c): Consider $\left(-9\right)÷3$.

$\left(-9\right)÷3=-3$

$\left(-9\right)÷3$ represents the integer since the value of $\left(-9\right)÷3$ is not in decimal.

Therefore, option (c) is incorrect.

Thus, options (a), (b), and (c) are incorrect.

Hence, option (d) is correct.
