Question

Miss Anne gave her students a number puzzle.
She asked, 'Which number when multiplied by 55 gives 55 as the product?'
Tap on the correct option.

• A. 0
• B. 2
• C. 1
• D. 3

Answer 1

The correct option is C 1

Any number multiplied by 0 gives 0 as the answer.

Consider: $55\times 0$ = 0
Therefore, 0 cannot be the correct option.

Consider: $55\times 2$ = 110
So, 2 cannot be the correct option.

Consider: $55\times 3$ = 165
So, 3 also cannot be the correct option.

Consider: $55\times 1$ = 55
Therefore, 1 is the correct option.

1 is also called the multiplicative identity.
