Ответ:

$1) \frac{48}{100} = \frac{4*12}{4*25} = \frac{12}{25}\\\\\frac{32}{48} = \frac{8*4}{8*6} = \frac{4}{6} = \frac{2}{3}\\\\\frac{14}{42} = \frac{2*7}{6*7} = \frac{2}{6} = \frac{1}{3}\\\\\frac{105}{600} = \frac{21*5}{120*5} = \frac{21}{120} = \frac{3*7}{3*40} = \frac{7}{40}\\\\\frac{45}{400} = \frac{5*9}{5*80} = \frac{9}{50}\\\\\frac{30}{75} = \frac{15*2}{15*5} = \frac{2}{5}\\\\\frac{45}{75} = \frac{15*3}{15*5} = \frac{3}{5}\\\\\frac{45}{225} = \frac{15*3}{15*15} = \frac{1}{5}$

$2) \frac{140}{450} = \frac{14*10}{45*10} = \frac{14}{45}\\\\\frac{220}{660} = \frac{220}{220*3} = \frac{1}{3}\\\\\frac{280}{520} = \frac{14*20}{26*20} = \frac{14}{26} = \frac{7}{13}\\\\\frac{105}{450} = \frac{15*7}{15*30} = \frac{7}{30}\\\\\frac{140}{680} = \frac{7*20}{34*20} = \frac{7}{34}\\\\\frac{135}{560} = \frac{27*5}{112*5} = \frac{27}{112}\\\\\frac{130}{390} = \frac{130}{130*3} = \frac{1}{3}\\\\\frac{200}{260} = \frac{20*10}{20*13} = \frac{10}{13}$
