Ответ:

1) $992\frac{11}{24}$

3) $715\frac{7}{16}$

Объяснение:

1) $1000-\frac{25}{8}+\frac{32}{243}*81=1000+\frac{32}{3}-\frac{25}{8}=1000-\frac{32*8-25*3}{24}= 1000-\frac{256-75}{24}=1000-\frac{181}{24}=1000-7\frac{13}{24}=992\frac{11}{24}$

3)$729-\frac{225}{16}+ \frac{27}{64}*\frac{32}{27} =729-14\frac{1}{16} +\frac{1}{2}=729-13\frac{9}{16} =715\frac{7}{16}$
