2. Which is greater \( \frac{-9}{20} \) or - 0.5 Explain how numbers on a number line.

To compare \( \frac{-9}{20} \) and -0.5, let’s first see where they fall on the number line. The fraction \( \frac{-9}{20} \) is equal to -0.45 when converted to decimal form, which places it to the right of -0.5 on a number line since -0.45 is greater than -0.5. Thus, \( \frac{-9}{20} \) is greater than -0.5. To visualize this better, remember that on a number line, numbers become more negative as you move left. So, while -0.5 sits to the left of -0.45, it clearly shows that \( \frac{-9}{20} \) is greater. It’s all about that left-right relationship!
