Let’s analyze each comparison one by one and explain the reasoning:

### a) \( \sqrt{5} \) and 2.5
1. Calculate \( \sqrt{5} \approx 2.236 \).
2. Compare: \( 2.236 < 2.5 \).
3. Conclusion: \( \sqrt{5} < 2.5 \).

**Reasoning**: Since \( \sqrt{5} \approx 2.236 \), which is less than 2.5, \( \sqrt{5} < 2.5 \).

### b) \( \sqrt{10} \) and \( 3 \frac{2}{3} \)
1. Calculate \( \sqrt{10} \approx 3.162 \).
2. Convert \( 3 \frac{2}{3} \) to a decimal: \( 3 \frac{2}{3} = 3.666 \).
3. Compare: \( 3.162 < 3.666 \).
4. Conclusion: \( \sqrt{10} < 3 \frac{2}{3} \).

**Reasoning**: Since \( \sqrt{10} \approx 3.162 \), which is less than \( 3.666 \), we have \( \sqrt{10} < 3 \frac{2}{3} \).

### c) 113% and \( \sqrt{1.2996} \)
1. Convert 113% to a decimal: 113% = 1.13.
2. Calculate \( \sqrt{1.2996} \approx 1.14 \).
3. Compare: \( 1.13 < 1.14 \).
4. Conclusion: \( 113\% < \sqrt{1.2996} \).

**Reasoning**: Since \( 1.13 < 1.14 \), \( 113\% < \sqrt{1.2996} \).

### d) 0.03% and \( \frac{3}{1000} \)
1. Convert 0.03% to a decimal: \( 0.03\% = 0.0003 \).
2. Convert \( \frac{3}{1000} \) to a decimal: \( \frac{3}{1000} = 0.003 \).
3. Compare: \( 0.0003 < 0.003 \).
4. Conclusion: \( 0.03\% < \frac{3}{1000} \).

**Reasoning**: Since 0.0003 is less than 0.003, \( 0.03\% < \frac{3}{1000} \).

### e) 0.0009 and 3%
1. Convert 3% to a decimal: \( 3\% = 0.03 \).
2. Compare: \( 0.0009 < 0.03 \).
3. Conclusion: \( 0.0009 < 3\% \).

**Reasoning**: Since 0.0009 is less than 0.03, \( 0.0009 < 3\% \).
