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.

Answer 1

No, if only one whole number is 1, then the product cannot be 1.

Examples:

(i) $5\times 1=5$

(ii) $4\times 1=4$

(iii) $8\times 1=8$

If both whole numbers are 1, then only their product will be 1.

$1\times 1=1$
