Aquí están las simplificaciones de las expresiones solicitadas, junto con el procedimiento que seguí para cada una:

### a. $$ \frac{3}{7}+3,6+\frac{4}{9}-2,9+14 $$

1. **Convertir a un denominador común**: Para sumar y restar fracciones, se necesita un denominador común. En este caso, el denominador común de $$7$$ y $$9$$ es $$63$$.
2. **Convertir las fracciones**:
   - $$ \frac{3}{7} = \frac{27}{63} $$
   - $$ \frac{4}{9} = \frac{28}{63} $$
3. **Sustituir y simplificar**:
   $$
   \frac{27}{63} + 3.6 + \frac{28}{63} - 2.9 + 14 = \frac{27 + 28}{63} + 3.6 - 2.9 + 14 = \frac{55}{63} + 3.6 - 2.9 + 14
   $$
4. **Calcular el resultado**:
   $$
   3.6 - 2.9 = 0.7 \quad \text{y} \quad 0.7 + 14 = 14.7
   $$
5. **Resultado final**:
   $$
   14.7 + \frac{55}{63} \approx 15.5\dot{7}3015\dot{8}
   $$

### b. $$ \sqrt{6}+7 \sqrt{6}-4-3 \sqrt{6}+\frac{1}{2} $$

1. **Combinar términos semejantes**:
   $$
   (1 + 7 - 3)\sqrt{6} - 4 + \frac{1}{2} = 5\sqrt{6} - 4 + 0.5
   $$
2. **Simplificar**:
   $$
   -4 + 0.5 = -3.5
   $$
3. **Resultado final**:
   $$
   5\sqrt{6} - 3.5 = \frac{10\sqrt{6}-7}{2}
   $$

### c. $$ \frac{\sqrt{3}}{3}-\sqrt{3}-\left(5 \sqrt{3}-\frac{\sqrt{3}}{4}\right) $$

1. **Expandir la expresión**:
   $$
   \frac{\sqrt{3}}{3} - \sqrt{3} - 5\sqrt{3} + \frac{\sqrt{3}}{4}
   $$
2. **Combinar términos semejantes**:
   $$
   \left(\frac{1}{3} + \frac{1}{4} - 1 - 5\right)\sqrt{3} = \left(\frac{4 + 3 - 12 - 60}{12}\right)\sqrt{3} = -\frac{65\sqrt{3}}{12}
   $$
3. **Resultado final**:
   $$
   -\frac{65\sqrt{3}}{12}
   $$

### d. $$ \left(\sqrt{2}+\sqrt{7}-\frac{3}{8} \sqrt{2}\right)+\sqrt{11}-8 \sqrt{7}+2 $$

1. **Combinar términos semejantes**:
   $$
   \left(1 - \frac{3}{8}\right)\sqrt{2} + (1 - 8)\sqrt{7} + \sqrt{11} + 2
   $$
2. **Simplificar**:
   $$
   \frac{5}{8}\sqrt{2} - 7\sqrt{7} + \sqrt{11} + 2
   $$
3. **Resultado final**:
   $$
   \frac{5\sqrt{2}-56\sqrt{7}+8\sqrt{11}+16}{8}
   $$

### e. $$ 2, \overline{8}+6, \overline{4}+12, \overline{4}-9,4 \overline{3} $$

1. **Convertir a fracciones**:
   - $$ 2.\overline{8} = \frac{28}{9} $$
   - $$ 6.\overline{4} = \frac{64}{9} $$
   - $$ 12.\overline{4} = \frac{124}{9} $$
   - $$ 9.4\overline{3} = \frac{94}{9} $$
2. **Sumar y restar**:
   $$
   \frac{28 + 64 + 124 - 94}{9} = \frac{122}{9} \approx 12.17
   $$
3. **Resultado final**:
   $$
   12.17
   $$

### f. $$ 0, \overline{20}+0, \overline{02}+0, \overline{002}-2, \overline{222} $$

1. **Convertir a fracciones**:
   - $$ 0.\overline{20} = \frac{20}{99} $$
   - $$ 0.\overline{02} = \frac{2}{99} $$
   - $$ 0.\overline{002} = \frac{2}{990} = \frac{1}{495} $$
   - $$ 2.\overline{222} = \frac{222}{99} $$
2. **Sumar y restar**:
   $$
   \frac{20 + 2 + \frac{2}{10} - 222}{99} = \frac{20 + 2 + 0.02 - 222}{99} = \frac{-200}{99} \approx -2
   $$
3. **Resultado final**:
   $$
   -2
   $$
