What should be added to a decimal to convert it correctly to a percentage if it requires more digits?

• A. No change needed
• B. Add extra zeros
• C. Multiply by 10
• D. Adjust the whole number

Answer: (B)

To convert a decimal to a percentage, the general approach involves multiplying the decimal by 100, which is equivalent to shifting the decimal point two places to the right. If the decimal requires more digits to accurately represent it as a percentage, adding extra zeros can help in this conversion process. For instance, if you have the decimal 0.05 and want to express it as a percentage, you would multiply it by 100 to get 5%. If the decimal representation were something like 0.005, you would still multiply it by 100, resulting in 0.5%, and you might need to add a zero to maintain clarity or formatting, particularly if the percentage representation needs to be shown with decimal places (e.g., converting 0.001 to 0.1%). Thus, when additional digits are beneficial for clarity in percentage format, adding extra zeros—whether to create placeholders or to increase precision—is the most effective method for achieving an accurate conversion to a percentage.
