Question

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

Answer 1

If only one number be 1 then the product cɑnnot be 1.

Exɑmples: 5 x 1 = 5, 4 x 1 = 4, 8 x 1 = 8

If both number ɑre 1, then the product is 1

1 x 1 = 1

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

• We need to justify the given statement

$\: \: \:$

$\Huge \bf \over \rightarrow\mid\ \bf{\underline{ \orange{Justification}}} \mid$

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:

• 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.
