  • Question
  • What is the product of a number and its reciprocal?


  • Options
  • A. 0
  • B. 1
  • C. -ve of the number
  • D. the number itself

  • Correct Answer


  • Explanation

    The product of a number and its reciprocal is always equals to 1.

     

    For Example : Let the number be 4.

    Now, its reciprocal is 1/4

    Hence, required product = 4 x 1/4 = 1.

     

    Now, take the number as -15.

    Then its reciprocal is -1/15

    Required product = -15 x -1/15 = 1.

     

    Hence, the product of a number and its reciprocal is 1.
