$\frac{8}{1} + \frac{15}{22} = \frac{176 + 15}{22} = \frac{191}{22}$
2)
$\frac{11}{35} + \frac{2}{1} = \frac{11 + 70}{35} \frac{81}{35}$

1)
$8\frac{4}{15} + 2 \frac{11}{15} = \frac{124}{15} + \frac{41}{15} = \frac{124 + 41}{15} = \frac{165}{15} = 11$
2)
$4 \frac{5}{9} + 3 \frac{7}{9} = \frac{41}{9} + \frac{34}{9} = \frac{41 + 34}{9} = \frac{75}{9} = \frac{25}{3}$

1)
$4 \frac{5}{23} = x = 10 \\ \frac{97}{23} + x = 10 \\ x = 10 - \frac{97}{23} \\ \frac{10}{1} - \frac{97}{23} = \frac{230 - 97}{23} = \frac{133}{23} \\ x = \frac{133}{23}$
Ответ:
$\frac{133}{23}$
