To change a percentage to a decimal, what operation do you perform with the decimal point?

• A. Move it two places to the right
• B. Leave it in place
• C. Move it two places to the left
• D. Multiply by 10

Answer: (C)

To convert a percentage to a decimal, you perform the operation of moving the decimal point two places to the left. This transformation is based on the fact that a percentage represents a part out of 100. For example, to convert 25% to a decimal, you would move the decimal point in 25 (which is 25.0 in decimal form) two places to the left, resulting in 0.25. This correctly reflects the relationship since 25% signifies 25 out of 100, which is equivalent to 0.25 in decimal form. Understanding this conversion is crucial in various mathematical contexts, including when calculating fractions of values or solving percentage-related problems. Moving the decimal point to the left effectively divides the percentage by 100, accurately converting it into its decimal equivalent.
