Solve the Ratio Problem: Converting 10:100 to Simplest Form

$10:100=$

To solve the problem of dividing $10$ by $100$, we'll follow these steps:

• Recognize the task as a division by 100.
• Understand that dividing by 100 effectively moves the decimal point two places to the left.
• Apply this understanding directly to the number $10$.

Let's work through these steps:

The number $10$ can be written as $10.0$, and dividing by $100$ means moving the decimal point two places to the left.
So, starting with $10.0$, we move the decimal:

$\text{Before: } 10.0$

$\text{After moving the decimal two places left: } 0.10$

Thus, $10:100 = 0.1$.

The correct answer is therefore: $0.1$.
