Answer 1

Объяснение:

$\frac{1}{7} *(\frac{14}{75} m+\frac{49}{25})+2\frac{1}{150} m-\frac{13}{50}=\frac{2}{75}m+\frac{7}{25}+\frac{301}{150}m-\frac{13}{50}=\frac{2*2+301}{150}m+\frac{7*2-13}{50} =\\=\frac{4+301}{150}m+\frac{14-13}{50} =\frac{305}{150}m+\frac{1}{50} =\frac{305*2}{305*150}+\frac{1}{50} =\frac{2}{150} +\frac{1}{50}=\\=\frac{2*1+1*3}{150}=\frac{2+3}{150}=\frac{5}{150} =\frac{1}{30}.$
