Convert the Ratio 1:100 to Its Decimal Equivalent

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

• Step 1: Start with the number 1, which can be written as $1.00$.

• Step 2: Since dividing by 100 is involved, we move the decimal point two places to the left, resulting in 0.01.

• Step 3: Identify the answer from the given choices.

Now, let's work through each step:
Step 1: Write the number 1 in decimal form as 1.00.
Step 2: Divide by 100 by moving the decimal point two places to the left.
- Moving one place to the left gives 0.10.
- Moving another place to the left gives 0.01.
Step 3: The resulting value is 0.01, which corresponds to choice 2.

Therefore, the solution to the problem is $0.01$.
