​

Answer 1

Ответ: $\frac{245}{6} , 40\frac{5}{6}$

Пошаговое объяснение:$6\frac{1}{4} × 8 - 3\frac{2}{3} × 5\frac{1}{2} + 2\frac{2}{5} × 4\frac{7}{12} = \frac{25}{4} × 8 - \frac{11}{3} × \frac{11}{2} + \frac{12}{5} × \frac{55}{12} = 50 - \frac{121}{6} + 11 = 61 - \frac{121}{6} = \frac{245}{6} = 40\frac{5}{6}$
