c) \( 6.8 \cdot 1000 \)

Did you know that the decimal system makes multiplying by 10, 100, and 1000 super easy? When you multiply \( 6.8 \) by \( 1000 \), you simply move the decimal point three places to the right! So, \( 6.8 \) becomes \( 6800 \). Voilà, just like magic! In real-world terms, this kind of multiplication is essential for calculations involving money. For instance, if someone earns \( 6.8 \) thousand dollars, knowing how to convert that to an actual dollar amount quickly helps in budgeting and making savings plans—achieving your financial goals just got a lot simpler!
