Answer 1

${\large{\red{\mapsto{\maltese{\underline{\green{\boxed{\blue{\underbrace{\overbrace{\pink{\pmb{\bf{Answer:}}}}}}}}}}}}}}$

Multiplicative Inverse of 5 is defined as what you can multiply with 5 to get 1. Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.2 multiplied by 5 equals 1. ... Therefore, the Multiplicative Inverse of -5 is -0.2.

Answer 2

Multiplicative Inverse of 5

Multiplicative Inverse

Multiplicative Inverse of 5 is defined as what you can multiply with 5 to get 1.

If the Multiplicative Inverse of 5 is x, the problem can be written as a function as follows:

5(x) = 1

Thus, to get the answer, we divide 1 by 5 like this:

1 / 5 = 0.2

Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.2 multiplied by 5 equals 1.

The Multiplicative Inverse of postive 5 has a positive answer and the Multiplicative Inverse of negative 5 has a negative answer. Therefore, the Multiplicative Inverse of -5 is -0.2.
