If the product of two whole numbers is 1, can we say that one or both of them will be 1? Justify through examples.


If the product of two numbers is 1, then both the numbers need to be 1.


Example -


1×1 = 1


However, if only one number is 1 then,


Example –


1×9 = 9


So,


We can say that the product of two whole numbers is 1 only when, both 1.
