вот ответ, и удачи)))

Пошаговое объяснение:

$1)10 \frac{7}{9} - 5 \frac{8}{9} = 4 \frac{8}{9} \\ 2)7 \frac{2}{7} + 11 \frac{2}{7} = 18 \frac{4}{7} \\ 3)21 \frac{1}{15} - 12 \frac{2}{15} = 8 \frac{14}{15} \\ 4)11 \frac{2}{9} + 7 \frac{7}{9} = 19 \\ 5)13 \frac{8}{9} - 9 = 4 \frac{8}{9} \\ 6)14 - 2 \frac{2}{3} = 11 \frac{1}{3} \\ 7)3 \frac{2}{5} + 7 \frac{3}{5} = 11$

Answer 2

Sure, I'd be happy to help you with these arithmetic calculations:

1. $10 \frac{7}{9} - 5 \frac{8}{9}$ Result: $4 \frac{7}{9}$

2. $7 \frac{2}{7} + 11 \frac{2}{7}$ Result: $18 \frac{4}{7}$

3. $21 \frac{1}{15} - 12 \frac{2}{15}$ Result: $8 \frac{11}{15}$

4. $11 \frac{2}{9} + 7 \frac{7}{9}$ Result: $18 \frac{1}{3}$

5. $13 \frac{8}{9} - 9$ Result: $3 \frac{8}{9}$

6. $14 - 2 \frac{2}{3}$ Result: $11 \frac{1}{3}$

7. $3 \frac{2}{5} + 7 \frac{3}{5}$ Result: $11 \frac{1}{5}$
