Answer 1

Step-by-step explanation:

Question:

Find the multiplicative inverse of -1.

What is multiplicative inverse?

When we inverse the number like if the number is 2 so it becomes 1/2 and if the number is 1/6 then the answer is 6.

More Examples:

Question 1:

⟹ -6/8

$⟹ \frac{8}{ - 6}$

Question 2 :

⟹ 12/14

$⟹ \frac{14}{12}$

Now let's come to the Question:

Solution:

-

⟹ -1

$⟹ \frac{1}{ - 1} \: \: ans..$

Points

• When we are doing multiplicative inverse so the sign does not change.
• Means if it is -4/7 so, it will become 7/-4 only .
• Not -7/4.
• The sign remains with the number only
• Basically we do the reciprocal of the number.

Answer 2

Therefore the multiplicative inverse of 1 is 11=1.

In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x−1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4. The reciprocal function, the function f(x) that maps x to 1/x, is one of the simplest examples of a function which is its own inverse (an involution).
