As an experienced tutor registered on UrbanPro.com, I understand the importance of addressing students' queries effectively. One such question that often arises is about the existence of a reciprocal for a particular rational number.


Identifying the Rational Number

The rational number in question is crucial to determine its reciprocal or lack thereof. In this case, the specific rational number is not provided, making it a generic inquiry.


Reciprocal of a Rational Number

  1. Reciprocal Definition:

    • The reciprocal of a number is another number that, when multiplied by the original number, results in the multiplicative identity (1).
  2. Existence of Reciprocal:

    • Most rational numbers have reciprocals.
    • Examples: Reciprocal of 2 is 1/2, and reciprocal of 5/3 is 3/5.
  3. Exception: No Reciprocal for Zero:

    • The only exception is the number 0.
    • Zero has no reciprocal since any number multiplied by 0 does not yield 1.

Addressing the Question

Given the information provided, it is likely that the question refers to the rational number zero.

  • The rational number with no reciprocal is 0.
    • Explanation: Any attempt to find the reciprocal of 0 leads to undefined results, as no number can be multiplied by 0 to produce 1.

Conclusion

In the context of rational numbers, it's essential for students to grasp the concept that, with the exception of zero, most rational numbers have reciprocals. This understanding contributes to their foundational knowledge in mathematics.
