Multiplicative Inverse of 820

Multiplicative Inverse of 820 is defined as what you can multiply with 820 to get 1.
If the Multiplicative Inverse of 820 is x, the problem can be written as a function as follows:
820(x) = 1
Thus, to get the answer, we divide 1 by 820 like this:
1 / 820 = 0.00121951
Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.00121951 multiplied by 820 equals 1.
The Multiplicative Inverse of postive 820 has a positive answer and the Multiplicative Inverse of negative 820 has a negative answer. Therefore, the Multiplicative Inverse of -820 is -0.00121951.
