Student A:In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1 / x or x, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a / b is b / a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1 / 5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4. The reciprocal function, the function f (x) that maps x to 1 / x, is one of the simplest examples of a function which is its own inverse (an involution).

Student B:OK... To answer the above question, the relevant sentence is: In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1 / x or x, is a number which when multiplied by x yields the multiplicative identity, 1.
