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

Answer:

We know that if a is any whole number, then \[a\times 1=a=1\times a\] It is clear that a must be = 1 Hence, both the numbers should be 1 i.e.,                   \[1\times 1=1\]
