Question

When we multiply a whole number and a multiplicative identity of whole numbers, then we get ______
A.The number itself
B.The multiplicative identity
C.0
D.Negative to that number

Answer 1

Hint: Whole number are positive integers. They start from 0 and go to infinity. Multiplication can increase the number by time the number is multiplied with. The multiplicative identity is to be known by students before going for the solution.

Complete step-by-step answer:
The question is given to find out the outcome of multiplying multiplicative identity.
The number in consideration here is the whole number. First of all we need to find the identity of a whole number.
Identity of a whole number ‘n’ is ‘1’.
In this case if a whole number ‘n’ is multiplied with its identity ‘1’
Hence, $ n \times 1$ will give us the same number itself.
After looking through the options given we can conclude that option (A) is correct.
So, the correct answer is “Option A”.

Note: The identity of a number is ‘1’. We need to understand the concept to get ahead with the solution. The solution then can be found out after understanding what operation needs to be done.
