Definition of multiplicative inverse:
the multiplicative inverse x' of a number x is x' such that x' multiplied by x equals one.
Setting up the equation:
x'*(-7) = 1
Using algebra to solve this equation for its unknown both sides are divided by negative seven to yield
x'=1/-7
Therefore the multiplicative inverse is negative one seventh.
To test this we multiply (1/-7) by (-7) and get 1. It works. :)
Derrick, you are abusing the service. You have asked 19 questions in very very introductory algebra and answered none. You are violating the TOS. You should be shunned.

the reciprocal, or multiplicative inverse, of a number x is the number which, when multiplied by x, yields 1. It is denoted 1/x or x-1.consider -1 as a superscript
-7*1/-7=1.
multiplicative inverse of -7=1/-7

Seriously, ask a tutor or a teacher.
It would be negative 1/7

It isalways the reciprocal of the given number i.e. (- 1/7)
