**Definition of Multiplicative Identity**

- Multiplicative Identity states that the product of any number and one (=1) is the number itself.

**More about Multiplicative Identity**

- Multiplicative identity is also called the identity property of one or the identity property of multiplication.

**Examples of Multiplicative Identity**

- 59 × 1 = 59 (As the number is multiplied by 1, the result is the number itself.)
*a*× 1 =*a*

**Solved Example on Multiplicative Identity**

Which number sentence illustrates the identity property of multiplication?

Choices:

A. 54 + 1 = 54

B. 54 × 1 = 55

C. 54 × 1 = 54

D. 54 × 1 = 0

Correct Answer: C

Solution:

Step 1:According to identity property of multiplication, the product of any number and 1 is the number itself.

Step 2:Here, only '54 × 1 = 54' satisfies the property.

Step 3:So, the number sentence '54 × 1 = 54' illustrates the identity property of multiplication.
