Convert Ratio to Decimal: Finding the Value of 13:100

To solve this problem, we'll divide 13 by 100 using the movement of the decimal point method:

• Step 1: Convert the integer 13 to a decimal by considering it as 13.0. This highlights the position where the decimal point begins.
• Step 2: Since we are dividing by 100, we need to move the decimal point two places to the left. Starting with 13.0:
• First move one place left: 1.30
• Second move one place left: 0.130
• Step 3: Thus, the final representation after moving two places to the left is 0.13.

Therefore, when dividing 13 by 100, the resulting decimal number is $0.13$.

The correct answer from the given choices is choice (3), which is $0.13$.
