Yes.
it means reciprocal, the number that multiplies by the original number to get a product of 1. The multiplicative inverse is always 1/x; x=5, then the multiplicative inverse is 1/5. If x=1/2 or .5, the multiplicative inverse is 1/.5, which is also 2.
The product of two rational numbers is always a rational number.
It is always rational.
The product of a rational and irrational number can be rational if the rational is 0. Otherwise it is always irrational.
Yes, it is.
If the multiplicative inverse exists then, by definition, the product is 1 which is rational.

multiplicative inverse of a number 'p' = 1/p
The multiplicative inverse is also known as the reciprocal. The multiplicative inverse of a number "x" can be expressed as 1/x. In the case of a fraction, exchange numerator and denominator to get the multiplicative inverse.
The multiplicative inverse of a number is the reciprocal of that number. In this case, the multiplicative inverse of 16 is 1/16. This is because when you multiply a number by its multiplicative inverse, the result is always 1.
Always, unless the original number is zero. This does not have an inverse.
Yes.
The multiplicative inverse of a complex number is the reciprocal of that number. To find the multiplicative inverse of 4 + i, we first need to find the conjugate of 4 + i, which is 4 - i. The product of a complex number and its conjugate is always a real number. Therefore, the multiplicative inverse of 4 + i is (4 - i) / ((4 + i)(4 - i)) = (4 - i) / (16 + 1) = (4 - i) / 17.
1/0.8 = 1.25
The product of two rational numbers is always a rational number.
Sometimes. Also, when depends on what you mean by "opposite": the additive inverse or the multiplicative inverse.
never a negative number * * * * * ... true if, by opposite, you mean the additive inverse. However, the multplicative inverse is also an opposite. And the multiplicative inverse of a negative number is always negative.
