Convert Ratio to Decimal: Solving 12:100 = ?

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

• Step 1: Interpret the division operation and use it.
• Step 2: Apply the division method by shifting the decimal.

Now, let's work through each step:
Step 1: The problem gives us the division operation $12:100$. We can represent this as $\frac{12}{100}$ or $12 \div 100$.
Step 2: When we divide 12 by 100, we shift the decimal point of 12 two places to the left. The number 12 can be written as 12.0 (with an implied decimal point), so shifting two places gives us 0.12.

Therefore, the result of $12:100$ is $0.12$.
