Multiplicative Inverse of 640

Multiplicative Inverse of 640 is defined as what you can multiply with 640 to get 1.
If the Multiplicative Inverse of 640 is x, the problem can be written as a function as follows:
640(x) = 1
Thus, to get the answer, we divide 1 by 640 like this:
1 / 640 = 0.0015625
Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.0015625 multiplied by 640 equals 1.
The Multiplicative Inverse of postive 640 has a positive answer and the Multiplicative Inverse of negative 640 has a negative answer. Therefore, the Multiplicative Inverse of -640 is -0.0015625.
