Explanation :
One(whole number 1) has a Mutiplicative Identity for Whole Numbers, i.e. when one(whole number 1) is multiplied with any given whole number, the resultant number is always equal to the given whole number.
In other words, One(whole number 1) does not affect any change in a multipication expression.
Study the following examples :
Example 1 : 4 × 1 = 4
Example 2 : 24 × 1 = 24
Example 3 : 888 × 1 = 888
Example 4 : 1 × 33 = 33
Example 5 : 1 × 9 = 9
Example 6 : 1 × 427 = 427
From the above examples you can learn that product of one(whole number 1) and any given whole number, always gives the result which is equal to the given whole number.
So we can say, One(whole number 1) has a Mutiplicative Identity for Whole Numbers
