4) 44.4

удачки!!

Пошаговое объяснение:

$2) \frac{5}{6} m + 2 = \frac{1}{3} m - 0.8 \\ \frac{5}{6} m - \frac{1}{3} m = - 0.8 - 2 \\ \frac{5}{6} m - \frac{2}{6} m = - 2.8 \\ \frac{3}{6} m = - 2.8 \\ \frac{1}{2} m = - 2.8 \\ m = - 2.8 \div \frac{1}{2} \\ m = - 2.8 \times 2 \\ m = - 5.6$

$4) \frac{7}{12} n - 3 = \frac{1}{2} n + 0.7 \\ \frac{7}{12} n - \frac{1}{2} n = 0.7 + 3 \\ \frac{7}{12} n - \frac{6}{12} n = 3.7 \\ \frac{1}{12} n = 3.7 \\ n = 3.7 \div \frac{1}{12} \\ n = 3.7 \times 12 \\ n = 44.4$
