5) \( \frac{2.5}{5} \)

Did you know that dividing decimals can be made easier by converting them into fractions? In your case, \( \frac{2.5}{5} = \frac{25}{50} \). This neat little trick shows how decimals simply transform into fractions—a skill that can simplify your calculations immensely! In real-world scenarios, knowing how to handle decimal division is super handy! Imagine you're at a coffee shop wanting to split the bill with a friend. If your total is $2.50 and you’re splitting it between two, you’d calculate \( \frac{2.5}{2} = 1.25 \) easily!
