Question

12целых2/10-4целых5/6

Answer 1

Пошаговое объяснение:

$12 \frac{2}{10} - 4 \frac{5}{6} = \frac{120 + 2}{10} - \frac{4 \times 6 + 5}{6 } = \frac{122}{10} - \frac{4 \times 6 + 5}{6} = \frac{61}{5} - \frac{4 \times 6 +5 }{6} = \frac{61}{5} - \frac{24 + 5}{6} = \frac{61}{5} - \frac{29}{6} = \frac{366}{30} - \frac{145}{30} = \frac{366 - 145}{30} = \frac{221}{30} = 7 \frac{11}{30}$
