вычисли

Answer 1

$3 \frac{1}{6} + ( - 8 \frac{3}{4} ) = \frac{19}{6} - 8 \frac{3}{4} = \frac{19}{6} - \frac{35}{4} = - \frac{67}{12} = - 5 \frac{7}{12}$

Answer 2

Пошаговое объяснение:

$3 \frac{1}{6} + ( - 8 \frac{3}{4} ) = \frac{18 + 1}{6} - \frac{8 \times 4 + 3}{4} = \frac{19}{6} - \frac{8 \times 4 + 3}{4} = \frac{19}{6} - \frac{32 + 3}{4} = \frac{19}{6} - \frac{35}{4} = \frac{38}{12} - \frac{105}{12} = \frac{38 - 105}{12} = - \frac{67}{12} = - 5 \frac{7}{12}$
