Помогите пожалуйста ​

Answer 1

$1) \: \: \: 14 \frac{1}{4} + 7 \frac{5}{6} = 14 + 7 + \frac{3 + 10}{12} = 21 \frac{13}{12} = 22 \frac{1}{12} \\ \\ 2) \: \: 14 \frac{11}{18} + 8 \frac{7}{12} = 14 + 8 + \frac{22 + 21}{36} = 22 \frac{43}{36} = 22 \frac{7}{36} \\ \\ 3) \: \: 7 \frac{5}{24} + 2 \frac{3}{16} = 7 + 2 + \frac{10 + 9}{48} = 9 \frac{19}{48} \\ \\ 4) \: \: 7 \frac{5}{16} + 4 \frac{1}{6} + 3 \frac{3}{8} = 7 + 4 + 3 + \frac{15 + 8 + 18}{48} = 14 \frac{41}{48}$
