Question

if a product of two whole number is one
​

Answer 1

Answer:

1 is the identity for multiplication of whole numbers or multiplicative identity for whole numbers. A number remain unchanged when multiplied by 1. Hence the product of two whole numbers will be equal to 1 if and only if both whole numbers are

Step-by-step explanation:

Given

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

Find out

We need to justify the given statement

Justification

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

If only one number be 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

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