Let’s go over the comparisons in the image to determine which are true.

1. $\sqrt{7} > 3.3$

   • $\sqrt{7} \approx 2.645751$, and $3.3$ is greater than this.
   • This is false.

2. $3\pi > 8$

   • $3\pi \approx 9.424777$, and $9.42 > 8$.
   • This is true.

3. $\sqrt{2} < \frac{7}{10}$

   • $\sqrt{2} \approx 1.414$, and $\frac{7}{10} = 0.7$.
   • Since $1.414 > 0.7$, this is false.

4. $\frac{5}{4} < 2$

   • $\frac{5}{4} = 1.25$, and $1.25 < 2$.
   • This is true.

5. $\sqrt{101} < 9.8$

   • $\sqrt{101} \approx 10.05$, and $10.05 > 9.8$.
   • This is false.

Correct Comparisons:

• $3\pi > 8$
• $\frac{5}{4} < 2$
