$1) 3 \frac{1}{15} +2 \frac{7}{25}$
Для сложения необходимо привести к одинаковому знаменателю
$3 \frac{5}{75} +2 \frac{21}{75} = 5 \frac{26}{75}$
$2) 2 \frac{7}{10} +9 \frac{2}{15} = 2 \frac{21}{30} +9 \frac{4}{30} = 11 \frac{25}{30} = 11 \frac{5}{6}$
$3) 9 \frac{5}{18} +6 \frac{1}{12} = 9 \frac{10}{36} +6 \frac{3}{36} = 15 \frac{13}{36} [tex]4) 1 \frac{7}{12}+3 \frac{5}{9} = 1 \frac{21}{36}+3 \frac{20}{36} = 4 \frac{41}{36} = 5 \frac{5}{36}$
$5) 5 \frac{5}{24}+2 \frac{1}{6} = 5 \frac{5}{24}+2 \frac{4}{24}= 7 \frac{9}{24} =7 \frac{3}{8}$
$6) 3 \frac{1}{12}+4 \frac{2}{15} = 3 \frac{5}{60}+4 \frac{8}{60} = 7 \frac{13}{60}$

Успехов в учебе!!!
