The image you uploaded contains a series of arithmetic expressions, each of which needs to be solved individually. I'll begin by solving the first few expressions for you. If you'd like, I can continue with more, or even all of them. Let's start:

1. Expression: $(7 - 6.35) : 6.5 + 9.9$

• First, calculate $7 - 6.35 = 0.65$.
• Then, divide by 6.5: $\frac{0.65}{6.5} = 0.1$.
• Finally, add 9.9: $0.1 + 9.9 = 10$.
• Solution: $10$

2. Expression: $\left( 12.36 : 1.2 + 0.25 - \frac{5}{16} \right)$

• First, divide 12.36 by 1.2: $\frac{12.36}{1.2} = 10.3$.
• Then, add 0.25: $10.3 + 0.25 = 10.55$.
• Subtract $\frac{5}{16}$: $10.55 - 0.3125 = 10.2375$.
• Solution: $10.2375$

3. Expression: $\left( \left( \frac{47}{72} \times 7 \right) : 1.25 - \frac{7}{40} \right)$

• First, multiply $\frac{47}{72}$ by 7: $\frac{47 \times 7}{72} = \frac{329}{72}$.
• Then, divide by 1.25: $\frac{329}{72 \times 1.25} = \frac{329}{90} \approx 3.6556$.
• Subtract $\frac{7}{40} = 0.175$: $3.6556 - 0.175 = 3.4806$.
• Solution: $3.4806$
