Question

If the product of two whole number is 1,can we say that one or both of them will be 1?justify through example?​

Answer 1

Answer:

If the two numbers’ product is one, then both numbers need to be equal to 1 only.

If only one number were 1, then the product cannot be 1.

Examples:

1 x 1 =1

Both the numbers are 1, and hence the product is 1

5 x 1 = 5

4 x 1 = 4

8 x 1 =8

One of the numbers is not equal to 1, and hence the product is not 1

Answer

Hence, If the product of two whole number is 1, then both the whole numbers should be 1.

Answer 2

If the product of 2 numbers is 1, then both the numbers have to equal to 1.

For example, 1×1=1

However, 1×6=6

Clearly, the product of two whole numbers will be 1 in the situation when both numbers to be multiplied are 1.
