Question – If the product of two whole numbers is 1, can we say that one or both of them will be 1? Justify through examples.
Solution
If the product of two whole numbers is 1, then both of them should be 1. This is so, because 1 is the multiplicative identity for whole numbers. Hence, any number multiplied by 1, gives the number itself. In order to obtain the product of two whole numbers as 1, 1 should be multiplied by itself.
