Fill in the blanks and state the property used.
`451+0="_______"+451`

Options

A. 0
Property used : associative identity
B. 0
Property used : multiplicative inverse
C. 0
Property used : Additive identity
D. 451
Property used : commutative identity

Answer

To solve the question, we need to fill in the blank in the equation \( 451 + 0 = "_______" + 451 \) and state the property used.

### Step-by-Step Solution:

1. **Identify the operation**: We are dealing with addition in this equation.

2. **Understand the additive identity property**: The additive identity property states that when you add 0 to any number, the result is that number itself. Mathematically, this can be expressed as:
\[ a + 0 = a \]
where \( a \) is any integer.

3. **Apply the property**: In our case, we have:
\[ 451 + 0 = 451 \]
This means that adding 0 to 451 does not change the value of 451.

4. **Fill in the blank**: According to the property, we can also write:
\[ 0 + 451 = 451 \]
Therefore, the blank can be filled with 0.

5. **Final equation**: Now we can rewrite the equation:
\[ 451 + 0 = 0 + 451 \]

6. **State the property used**: The property used in this equation is the **Additive Identity Property**.

### Final Answer:
The filled equation is:
\[ 451 + 0 = 0 + 451 \]
The property used is the **Additive Identity Property**.
