How do you convert decimals to percentages?

• A. By adding 100
• B. By multiplying by 10
• C. By moving the decimal point
• D. By dividing by 100

Answer: (C)

To convert decimals to percentages, the correct method is to move the decimal point two places to the right. This action effectively transforms the decimal into a percentage. For instance, if you have the decimal 0.75, moving the decimal point two places to the right changes it to 75. This signifies that 0.75 is equivalent to 75%. This method works because percentages are based on a whole that represents 100. When you shift the decimal place, you are recalibrating the representation of the number from a fraction of 1 (as in decimals) to a fraction of 100 (as in percentages). Understanding this concept is crucial for applying it in various mathematical problems, especially in contexts like finance, statistics, and real-world applications where percentages are commonly used.
