d) \( \frac{5 x}{10 x} \)

Did you know that simplifying fractions is like being a detective? In this case, the \(x\) in both the numerator and denominator can be canceled out, leaving you with \( \frac{5}{10} \), which further simplifies to \( \frac{1}{2} \). So, your expression simplifies to a nice and neat \( \frac{1}{2} \)! In real life, simplifying fractions is super handy! Whether you're splitting a pizza (yummy!) or dividing up a budget, knowing how to reduce fractions makes it easier to understand and manage ratios. It's like having a superpower that allows you to make sense of the world—with less math clutter! 🍕💰
