Which of the following is the reciprocal of the reciprocal of a ration...
Explanation:
The multiplicative identity of any number is the number that when multiplied by that number gives the number itself. In other words, it is the number that does not change the value of the number when multiplied by it.
For example, the multiplicative identity of 5 is 1, since 5 multiplied by 1 is 5. Similarly, the multiplicative identity of any rational number is 1, since any rational number multiplied by 1 gives the same rational number.
Therefore, the correct answer to the given question is option A, which is 1.
Example:
Let's take an example of a rational number, say 3/4.
Multiplying this number by 1 gives:
3/4 x 1 = 3/4
So, we can see that the value of the rational number remains unchanged when multiplied by 1.
Conclusion:
The multiplicative identity of any rational number is 1. This is because 1 does not change the value of any rational number when multiplied by it.
