    Let b be the multiplicative inverse of a such ab=1

    S the multiplicative inverse of -1/9 is b and a is -1/9 Solve for the multiplicative inverse of -1/9

    In other words, solve for b

    ab=1 a*b=1 -1/9 * b=1 <---solve for b Can you do this?

    Your question ask us to find the multiplicative inverse of a I'm calling that multiplicative inverse b. The multiplicative identity is 1. If a and b are multiplicative inverses of each other, then the product of a and b is 1.

    ab=1 -1/9 * b=1 You need to solve this for b in other words.

    If you don't know how to solve equations, then you can always remember to take the opposite of the reciprocal. Just so you know 0 doesn't have a multiplicative inverse.

    To find the reciprocal just switch the numerator and denominator for each other.

    Opposite of the reciprocal? Multiplicative inverse IS reciprocal.

    Oops. I'm thinking of lines that are perpendicular. I'm sorry.

    But still ab=1 then a and b are multiplicative inverses of each other
