Answer 1

\( \color{Black}{\Rightarrow \Large {-1 \over 9} \times x = 1 }\)

Solve for \(x\).

Answer 2

Another way to do it is to just flip the fraction :D

Answer 3

The multiplicative inverse of a is 1/a and the multiplicative indentity of a number is 1, that is, once you carry out the operation you should get back the original/identity which is 1. Thus the inverse is -9

Answer 4

its multiplicative inverse is -9
