Solve the Decimal Division: 2.2 ÷ 10 Step by Step

$2.2:10=$

To solve this problem, let's follow these steps:

• Step 1: Identify the given number and divisor.
• Step 2: Understand how dividing by 10 affects decimal placement.
• Step 3: Perform the division and verify the result with the choices provided.

Now, let's work through each step:

Step 1: The problem gives us the number $2.2$ and requires dividing it by $10$.

Step 2: When dividing a number by $10$, you move the decimal point one place to the left. This is a result of how the base-10 system works; dividing by a power of 10 shifts the decimal point left.

Step 3: In the number $2.2$, the decimal is currently after the numeral "2." Moving the decimal one place left, we have:

$2.2 \rightarrow 0.22$

Therefore, the result of $2.2 \div 10$ is $\textbf{0.22}$.

To ensure accuracy, we compare this result with the provided choices. Choice number 3, $0.22$, matches our solution.

Thus, the solution to the problem is $0.22$.
