а) $\frac{10}{100} = \frac{1}{10}$;
б) $\frac{20}{80} = \frac{1}{4}$;
в) $\frac{20}{100} = \frac{1}{5}$;
г) $\frac{20}{600} = \frac{1}{30}$;
д) $\frac{100}{1000} = \frac{1}{10}$;
е) $\frac{200}{500} = \frac{2}{5}$;
ж) $\frac{60}{200} = \frac{3}{10}$;
з) $\frac{80}{400} = \frac{1}{5}$.
$\frac{10}{100} = \frac{10 : 10}{100 : 10} = \frac{1}{10}$
$\frac{20}{80} = \frac{20 : 20}{80 : 20} = \frac{1}{4}$
$\frac{20}{100} = \frac{20 : 20}{100 : 20} = \frac{1}{5}$
$\frac{20}{600} = \frac{20 : 20}{600 : 20} = \frac{1}{30}$
$\frac{100}{1000} = \frac{100 : 100}{1000 : 100} = \frac{1}{10}$
$\frac{200}{500} = \frac{200 : 100}{500 : 100} = \frac{2}{5}$
$\frac{60}{200} = \frac{60 : 20}{200 : 20} = \frac{3}{10}$
$\frac{80}{400} = \frac{80 : 80}{400 : 80} = \frac{1}{5}$
