1. \( \frac{7}{9} + \frac{5}{18} = \frac{7 \cdot 2}{9 \cdot 2} + \frac{5}{18} = \frac{14}{18} + \frac{5}{18} = \frac{19}{18} = 1 \frac{1}{18} \)
2. \( 7 \frac{2}{5} + 4 \frac{1}{3} = \frac{37}{5} + \frac{13}{3} = \frac{37 \cdot 3}{5 \cdot 3} + \frac{13 \cdot 5}{3 \cdot 5} = \frac{111}{15} + \frac{65}{15} = \frac{176}{15} = 11 \frac{11}{15} \)
3. \( 6 \frac{7}{24} + 2 \frac{5}{16} = \frac{151}{24} + \frac{37}{16} = \frac{151 \cdot 2}{24 \cdot 2} + \frac{37 \cdot 3}{16 \cdot 3} = \frac{302}{48} + \frac{111}{48} = \frac{413}{48} = 8 \frac{29}{48} \)
