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.
