How can a decimal be converted into a percent?

• A. Add 10 to the decimal
• B. Multiply by 100 and add the % sign
• C. Divide by 100 and remove the % sign
• D. Convert into a fraction first

Answer: (B)

To convert a decimal into a percent, you multiply the decimal by 100 and then add the percent sign. This process is based on the definition of a percent, which means "per hundred." Therefore, when you multiply a decimal by 100, you are determining how many parts out of 100 it represents and expressing it in a convenient and familiar format—percentages. For example, if you take the decimal 0.75 and multiply it by 100, you get 75. By then adding the percent sign, you convert it into 75%, which represents 75 out of 100 parts. This method allows for a straightforward transformation from decimal form to a percentage format that can easily be interpreted in various contexts, such as financial calculations or statistical data.
