1) a) $$rac{1,5}{9} = \frac{15}{90} = \frac{1}{6}$$
б) $$rac{7,2}{8} = \frac{72}{80} = \frac{9}{10} = 0,9$$
в) $$rac{0,8}{6} = \frac{8}{60} = \frac{2}{15}$$
г) $$rac{1,4}{35} = \frac{14}{350} = \frac{1}{25} = 0,04$$
2) a) $$rac{4,8}{3,2} = \frac{48}{32} = \frac{3}{2} = 1,5$$
б) $$rac{2,1}{12,6} = \frac{21}{126} = \frac{1}{6}$$
в) $$rac{0,07}{14,7} = \frac{7}{14700} = \frac{1}{2100}$$
г) $$rac{0,12}{4,5} = \frac{12}{450} = \frac{2}{75}$$
