Multiplicative Inverse of 645

Multiplicative Inverse of 645 is defined as what you can multiply with 645 to get 1.
If the Multiplicative Inverse of 645 is x, the problem can be written as a function as follows:
645(x) = 1
Thus, to get the answer, we divide 1 by 645 like this:
1 / 645 = 0.00155039
Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.00155039 multiplied by 645 equals 1.
The Multiplicative Inverse of postive 645 has a positive answer and the Multiplicative Inverse of negative 645 has a negative answer. Therefore, the Multiplicative Inverse of -645 is -0.00155039.
