IN ALGEBRA muliplicative Inverse is the product of the number and the reiprocal of the number and after multiplying the number and the reciprocal the result will be 1.
If the multiplicative inverse exists then, by definition, the product is 1 which is rational.
Always, unless the original number is zero. This does not have an inverse.
The additive inverse of EVERY positive rational number is a negative number.
No. The additive inverse of zero or a negative rational number is not negative.
of course
No, it is not. 3/5 is rational and its multiplicative inverse is 5/3 which is not an integer.
Zero.
