Select the expression that is the multiplicative inverse of n, where n is a non-zero number. a. 1n b. -n c. -1n d. 2n

multiplicative inverse of n

1/n

I am assuming that is A and you don't have the fraction bar

A.

Step-by-step explanation:

The multiplicative inverse refers to the same number but in the opposite position, if the number is a numerator, then its multiplicative opposite is at the denominator. Basically, it consists in turning around the order of the fraction.

The formal definition is that a number is a multiplicative inverse of another if their product gives the neutral multiplicative element which is 1. Let's try:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
