Solve the Ratio Equation: Converting 1.2:100 to Decimal Form

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

• Step 1: Identify the given information, which is the number 1.2 and that we need to divide it by 100.
• Step 2: Recognize that dividing by 100 means moving the decimal point in 1.2 two places to the left.
• Step 3: Shift the decimal point two places to the left in 1.2, resulting in 0.012.

Now, let's work through this solution in detail:

Step 1: We begin with the number 1.2.
Step 2: To divide by 100, visualize the decimal point moving two places left. Since 1.2 is represented as 1.2 (or 1.20 for easier visualization), the decimal point moves past the "1" and an extra zero is added in front:
- Original: 1.2
- First move: 0.12
- Second move: 0.012

Therefore, the solution to the problem is $0.012$.
