1) 3 2/7+5 3/14
$3 \frac{2}{7} +5 \frac{3}{14} =3 \frac{4}{14} +5 \frac{3}{14} =3+5+ \frac{4+3}{14} =8 \frac{7}{14} =8 \frac{1}{2}$

2) 5 7/8+2 5/12
$5 \frac{7}{8} +2 \frac{5}{12} =5 \frac{21}{24} +2 \frac{10}{24} =5+2+ \frac{21+10}{24} =7 \frac{31}{24} =8 \frac{7}{24}$

3) 7 3/8+1 5/6
$7 \frac{3}{8} +1 \frac{5}{6} =7 \frac{9}{24} +1 \frac{20}{24} =7+1+ \frac{9+20}{24} =8 \frac{29}{24} =9 \frac{5}{24}$
