помогите пожалуйста СпАМ БаН

Answer 1

Ответ:

Пошаговое объяснение:

= 5/12(48/10m - 6/5n) - 36/10(4/9m + 15/10n) =

(5/12*48/10m - 5/12*6/5n) - (36/10*4/9m + 36/10*15/10n) =

(1/1 * 4/2m - 1/2 * 1/1n) - (4/5 * 2/1m + 18/2 * 3/5n) =

(2m - 1/2n) - (8/5m + 54/10n) =

2m - 1/2n - 1. 3/5m - 5. 4/10n =

1. 5/5m - 5/10n - 1. 3/5m - 5. 4/10n =

2/5m - 5. 9/10n

Answer 2

Пошаговое объяснение:

$\\ \\ \frac{5}{12} ( \: 4.8m - 1 \frac{1}{5} n) - 3.6( \frac{4}{9}m + 1.5n) \\ \\ \frac{5}{12} ( \frac{48}{10} m - \frac{6}{5} n) - \frac{36}{10} ( \frac{4}{9} m + \frac{15}{10} n) \\ \\ \frac{5}{12}( \frac{24}{5} m - \frac{6}{5} n) - \frac{18}{5} ( \frac{4}{9} m + \frac{3}{2} n) \\ \\ \frac{5}{12} \times \frac{24}{5} m - \frac{5}{12} \times \frac{6}{5} n - \frac{18}{5} \times \frac{4}{9} m - \frac{18}{5} \times \frac{3}{2} n \\ \\ 2m - \frac{1}{12} \times 6n - \frac{2}{5} \times 4m - \frac{9}{5} \times 3n \\ \\ 2m - \frac{1}{2} n - \frac{8}{5} m - \frac{27}{5} n \\ \\ \frac{2m}{1} - \frac{8m}{5} - \frac{n}{2} - \frac{27n}{5} \\ \\ \frac{5 \times 2m}{5} - \frac{8m}{5} - \frac{5n}{5 \times 2} - \frac{2 \times 27n}{2 \times 5} \\ \\ \frac{10m - 8m}{5} - \frac{5n}{10} - \frac{54n}{10} \\ \\ \frac{2}{5} m - \frac{59}{10} n \\ \\ 0.4m - 5.9n$
