\( \$ 100 \div 20 \)

Did you know that dividing $100 by 20 gives you $5? That's right! This simple calculation can be applied to everyday scenarios, like determining how much each person would pay if you were splitting a dinner bill among 20 friends. Just imagine the laughter and the generous piles of nachos that could follow! A common mistake when dividing numbers is forgetting to check your arithmetic. It's easy to get ahead of yourself, so take a moment to ensure your calculations make sense. If you get confused, try visualizing it as splitting up a pizza; with each slice representing part of the whole, you’ll always find the right answer deliciously!
