Solve the Division Problem: Calculate 450 ÷ 450

To solve this problem, we will follow these steps:

• Step 1: Identify the given numbers: 450 and 450.
• Step 2: Apply the division property of numbers that states dividing a non-zero number by itself results in 1.

Now, let's work through each step:

Step 1: The given expression is $450 \div 450$.
Step 2: Using the property $a \div a = 1$ for any $a \neq 0$, we apply it here where $a = 450$. Thus, $450 \div 450 = 1$.

Therefore, the solution to the problem is $1$.
