In a set S, the multiplicative inverse of a non-zero element x is an element of the set, y, such that x*y = y*x = i, the identity element of S. For the set of numbers, the multiplicative identity is 1 and the multiplicative identity is also denoted by 1/x or x^-1.

Is multiplicative inverse and reciprocal have the same definition?
Yes.
Why Is the product of a fraction and its multiplicative inverse 1?
The statement is true only for non-zero fractions and it follows from the definition of a multiplicative inverse.
How do you determine the multiplicative inverse of a number?
The multiplicative inverse of a number is its reciprocal, meaning the multiplicative inverse of the rational number a/b is b/a. In the specialized case for integers, the multiplicative inverse of n is 1/n. This is due to the fact that a/b * b/a = 1 and n * 1/n = 1, which is the definition of a multiplicative inverse. More succinctly, to find the multiplicative inverse you "flip" the fraction or integer around to its reciprocal. This is the number that when multiplied with the original number results in a product of 1.
What is an multiplicative inverse of -.50?
The multiplicative inverse is 1/(-0.50) = -2
Multiplicative inverse of a negative number?
The multiplicative inverse is the negative of the reciprocal of the positive value. Thus the multiplicative inverse of -7 is -1/7.
Multiplicative inverse is the definition of what word?
cross multiply
Is multiplicative inverse and reciprocal have the same definition?
Yes.
Why Is the product of a fraction and its multiplicative inverse 1?
The statement is true only for non-zero fractions and it follows from the definition of a multiplicative inverse.
Is the product of a number and its multiplicative inverse always a rational number?
If the multiplicative inverse exists then, by definition, the product is 1 which is rational.
What is multiplicative inverse of 0?
There is no multiplicative inverse of 0. By definition, when you multiply a number by its multiplicative inverse, the product is 1. However, when you multiply 0 by anything, the product is 0. Those two statements could not logically co-exist if there were any multiplicative inverse of 0, so there is no such thing.
What is the multiplicative of -1?
Assuming the question is about the multiplicative inverse, the answer is, -1. It is its own multiplicative inverse.

What is the multiplicative inverse of 4 i?
The multiplicative inverse of 4i is -(1/4)*i.
What is the multiplicative inverse of −100?
the multiplicative inverse of -100 is 1/-100
What is an multiplicative inverse of -.50?
The multiplicative inverse is 1/(-0.50) = -2
Name the additive inverse and the multiplicative inverse for the number 2.5?
Additive inverse: -2.5 Multiplicative inverse: 0.4
What is zero product property?
Multiplicative Inverse of a NumberReciprocal The reciprocal of x is . In other words, a reciprocal is a fraction flipped upside down. Multiplicative inverse means the same thing as reciprocal. For example, the multiplicative inverse (reciprocal) of 12 is and the multiplicative inverse (reciprocal) of is . Note: The product of a number and its multiplicative inverse is 1. Observe that ·= 1.
