Question

rational number that does not have a multiplicative inverse which property is this

Answer 1

MULTIPLICATIVE INVERSE

Answer 2

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. Therefore, rational number 0 has no reciprocal or multiplicative inverse.
