Answer 1

Ответ:

1)$19 \frac{5}{6} - 6 \frac{1}{12} - 2 \frac{7}{9} = \frac{119}{6} - \frac{73}{12} - \frac{25}{9} = \frac{395}{36} \\ 2)9 \frac{14}{15} - 2 \frac{1}{5} - 4 \frac{7}{10} = (9 - 2 - 4) \times ( \frac{14}{15} - \frac{1}{5} - \frac{7}{10} ) = 3 \frac{1}{10} = \frac{91}{10} \\ 3)28 \frac{1}{20} - (7 - 2 \frac{8}{15} ) = \frac{561}{20} - (7 - \frac{38}{15} = \frac{561}{20} - \frac{67}{15} = \frac{283}{12}$

Answer 2

Ответ:

Пошаговое объяснение:

1.

= 19. 30/36 - 6. 3/36 - 2. 28/36 = 13. 27/36 - 2. 28/36 = 12. 63/36 - 2. 28/36 =

10. 35/36

2)

= 9. 28/30 - 2. 6/30 - 4. 21/30 = 7. 22/30 - 4. 21/30 = 3. 1/30

3)

= 28. 3/60 - (6. 60/60 - 2. 32/60) = 28. 3/60 - 4. 28/60 = 27. 63/60 - 4. 28/60 = 23. 35/60 = 23. 7/12
