Выполним сложение дробей:

1. $$4 \frac{15}{32} + 8 \frac{17}{32} = (4+8) + (\frac{15}{32} + \frac{17}{32}) = 12 + \frac{15+17}{32} = 12 + \frac{32}{32} = 12 + 1 = 13$$
2. $$29 \frac{6}{19} + 6 \frac{18}{19} = (29+6) + (\frac{6}{19} + \frac{18}{19}) = 35 + \frac{6+18}{19} = 35 + \frac{24}{19} = 35 + 1\frac{5}{19} = 36\frac{5}{19}$$
3. $$38 \frac{29}{43} + 24 \frac{22}{43} = (38+24) + (\frac{29}{43} + \frac{22}{43}) = 62 + \frac{29+22}{43} = 62 + \frac{51}{43} = 62 + 1\frac{8}{43} = 63\frac{8}{43}$$

Ответ: 1) $$13$$, 2) $$36\frac{5}{19}$$, 3) $$63\frac{8}{43}$$
