Вычислите: (8 7/12-2 17/36)*2,7-4 1/3:0,65.

Ответ:

\[\left( 8\frac{7}{12} - 2\frac{17}{36} \right) \cdot \frac{27}{10} - \frac{13}{3}\ :\frac{13}{20} =\]

\[= \frac{220}{36} \cdot \frac{27}{10} - \frac{13 \cdot 20}{3 \cdot 13} = \frac{33}{2} - \frac{20}{3} =\]

\[= \frac{99}{6} - \frac{40}{6} = \frac{59}{6} = 9\frac{5}{6}\]
