Question

multipicate Inverse of rational number ​

Answer 1

Answer:

The rational number b/a is called the multiplicative inverse or reciprocal of a/b and is denoted by (a/b)-1. ... 1 and -1 are the only rational numbers which are their own reciprocals. No other rational number is its own reciprocal. We know that there is no rational number which when multiplied with 0, gives 1.
