Question

The multiplicative inverse of -87​

Answer 1

-1/87

Explanation:

The multiplicative inverse is just a number reversed. A whole number, when being multiplied by a fraction, is written over 1.

Let's say that number is 2. 2 becomes 2/1 and the multiplicative inverse would be 1/2.

Answer 2

Multiplicative Inverse of 87 is defined as what you can multiply with 87 to get 1.

If the Multiplicative Inverse of 87 is x, the problem can be written as a function as follows:

87(x) = 1

Thus, to get the answer, we divide 1 by 87 like this:

1 / 87 = 0.01149425

Note that the answer is rounded to the nearest 8 decimals if necessary. We can prove that the answer is correct: 0.01149425 multiplied by 87 equals 1.

The Multiplicative Inverse of postive 87 has a positive answer and the Multiplicative Inverse of negative 87 has a negative answer. Therefore, the Multiplicative Inverse of -87 is -0.01149425.
