Which of the following operations is used to convert a percentage to a decimal?

• A. Add 100
• B. Multiply by 1/100
• C. Divide by 10
• D. Subtract 50

Answer: (B)

To convert a percentage to a decimal, you take the percentage value and divide it by 100. This process effectively transforms the percentage into a fraction of 100. For example, if you have 25%, converting it to a decimal involves calculating \( \frac{25}{100} \), which equals 0.25. Multiplying by 1/100 achieves the same result, as it is mathematically equivalent to dividing by 100. Therefore, using this operation accurately changes a percentage into a decimal, making it the correct method for this conversion. Understanding this operation is key in various mathematical calculations, especially when dealing with proportions, financial calculations, or any situation where percentages need to be expressed in decimal form for further mathematical operations.
