Andy's savings account pays \( 0.3 \% \) more interest than Marty's. What is \( 0.3 \% \) written as a decimal number? 0.003 0.3 0.0003 0.03

To convert a percentage to a decimal, you divide by 100. So, \( 0.3\% \) is calculated as \( 0.3 \div 100 = 0.003 \). This means that in decimal form, \( 0.3\% \) is equivalent to \( 0.003 \) – just a tiny fraction when you think about it! Now let’s think about how this could apply in real life! Suppose Andy has a savings account with a balance of $5,000. If his account earns \( 0.3\% \) more interest than Marty’s account, that extra \( 0.003 \) added to the interest rate can lead to a bigger difference in the interest earned over time, potentially turning into a nice little nest egg as years go by. It's amazing how small percentages can make a big impact!
