This should be the correct answer
The expression that is equal to -4 is D 16/-4 which means option D is correct. ( it should be noted that option D is not written properly)
<h3>Why is that 4 is equals to 16
/-4?</h3>
In a mathematical expression when as negative vale is been used to multiply a negative value, then we will have a positive values , same thing with when a negative value is used to multiply a positive value, a negative value will be gotten.
In the case of the question, if positive value is used to divide a negative value, a negative value will be gotten, hence expression that is equal to -4 is 16/-4 which is means optionD is correct.
Therefore, option C is correct.
