To order the values from least to greatest, we first need to find their approximate decimal representations:
- \( \pi \) (approximately 3.14)
- \( \sqrt{6} \) (approximately 2.45)
- \( \frac{7}{2} = 3.5 \)
- \( 3.25 \)
Now, ordering these values:
- \( \sqrt{6} \approx 2.45 \)
- \( \pi \approx 3.14 \)
- \( 3.25 \)
- \( \frac{7}{2} = 3.5 \)
So, from least to greatest, the order is:
\[ \sqrt{6}, \pi, 3.25, \frac{7}{2} \]
