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

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