**Multiplicative Inverse of 20**

Multiplicative Inverse of 20 is defined as what you can multiply with 20 to get 1.

If the Multiplicative Inverse of 20 is x, the problem can be written as a function as follows:

20(x) = 1

Thus, to get the answer, we divide 1 by 20 like this:

1 / 20 = 0.05

Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.05 multiplied by 20 equals 1.

The Multiplicative Inverse of postive 20 has a positive answer and the Multiplicative Inverse of negative 20 has a negative answer. Therefore, the Multiplicative Inverse of -20 is -0.05.
