so far as i know: the inverse of X is 1/X
by iwnit on November 16th, 2009
"In many contexts in mathematics the term inverse indicates the opposite of something. This word and its derivatives are used greatly in mathematics, as illustrated below.
Inverse element of an element x with respect to a binary operation * with identity element e is an element y such that x * y = y * x = e. In particular,
- the additive inverse of x is –x;
- the multiplicative inverse of x is x^–1."

Divide it into one. Inverse of x is 1/x.

The inverse, also known as the reciprocal, of a number is, as loopyfruit says, 1/x. So the inverse of 2 is 1/2 = 0.5, the inverse of 3 is 1/3 = 0.33333..... etc.
