3 1/2 + 4 2/3

Answer 1

$1) \\ (19 + 6) + ( \frac{5}{18} + \frac{1}{12} ) = 25 + \frac{13}{36} = 25 \frac{13}{36} \\ \\ 2) \\ (15 + 8) + ( \frac{1}{21} + \frac{1}{28} ) = 23 + \frac{1}{12} = 23 \frac{1}{12} \\ \\ 3) \\ (3 + 4) + ( \frac{1}{2} + \frac{2}{3} ) = 7 + \frac{7}{6} = 7 + 1 \frac{1}{6} = 7 + 1 + \frac{1}{6} = 8 + \frac{1}{6} = 8 \frac{1}{6}$
