Answer 2

Sure, I can help you with these arithmetic calculations. Let's go through each one step by step:

1. 1/2 + 1/3: To add these fractions, we need a common denominator, which is 6 in this case: $\frac{3}{6} + \frac{2}{6} = \frac{5}{6}$

2. 3/4 + 2/5: We need a common denominator, which is 20 in this case: $\frac{15}{20} + \frac{8}{20} = \frac{23}{20}$ or $1 \frac{3}{20}$ in mixed number form.

3. 1/8 + 1/4: We need a common denominator, which is 8 in this case: $\frac{1}{8} + \frac{2}{8} = \frac{3}{8}$

4. 1/4 + 2/5: We need a common denominator, which is 20 in this case: $\frac{5}{20} + \frac{8}{20} = \frac{13}{20}$

5. 5/7 - 1/6: To subtract these fractions, we need a common denominator, which is 42 in this case: $\frac{30}{42} - \frac{7}{42} = \frac{23}{42}$

6. 2/5 - 5/9: We need a common denominator, which is 45 in this case: $\frac{18}{45} - \frac{25}{45} = -\frac{7}{45}$ or $-\frac{1}{9}$ in mixed number form.
