Solve the Division Equation: Finding the Number Where ?:1 = 0

To solve this problem, we'll follow these steps:

• Step 1: Understand the problem statement meaning $x \div 1 = 0$.
• Step 2: Apply the division property: any number divided by 1 remains unchanged.
• Step 3: Recognize that since $x \div 1 = x$, for it to equal 0, $x$ must indeed be 0.

Now, let's work through each step:
Step 1: The equation $x \div 1 = 0$ implies that $x$ divided by 1 equals 0.
Step 2: According to the division rule, $x = x \div 1$. So for $x \div 1$ to be zero, $x$ must be 0.
Step 3: Solving for $x$, we find that since $x = 0 \div 1$, it naturally simplifies to $x = 0$ because zero divided by any number is zero.

Therefore, the solution to the problem is $x = 0$.
