Question

Which of the following illustrates the multiplicative identity?

• A.
  45 + 0 = 45
• B.
  15 x 2 = 30
• C.
  16 x 1 = 16
• D.
  5 x 0 = 0

Answer 1

The correct option is C

16 x 1 = 16
Multiplicative identity : When 1 is multiplied with any given whole number, the resultant number is always equal to the given whole number.

Hence, 1 is called the multiplicative identity.
So, 16 x 1 = 16 illustrates the multiplicative identity.
