The value of n such that the number n and -3/4 are additive inverses is 3/4
<h3>How to determine the value of n?</h3>
The statement is given as:
The number n and -3/4 are additive inverses
The above statement means that
n = -1 * -3/4 --- by the definition of additive inverses
Next, we evaluate the product of -1 and -3/4
n = 3/4
Hence, the value of n such that the number n and -3/4 are additive inverses is 3/4
