Помогите пожалуйста

Answer 1

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