1) $5\% = 5 \cdot \frac{1}{100} = \frac{5}{100} = \frac{1}{20}$
$4\frac{1}{6}\% = 4\frac{1}{6} \cdot \frac{1}{100} = \frac{25}{6} \cdot \frac{1}{100} =$
$= \frac{25 \cdot 1}{6 \cdot 100} = \frac{1}{24}$
$13\frac{1}{3}\% = 13\frac{1}{3} \cdot \frac{1}{100} = \frac{40}{3} \cdot \frac{1}{100} =$
$= \frac{40 \cdot 1}{3 \cdot 100} = \frac{2}{15}$
$44\frac{4}{9}\% = 44\frac{4}{9} \cdot \frac{1}{100} = \frac{400}{9} \cdot \frac{1}{100} =$
$= \frac{400 \cdot 1}{9 \cdot 100} = \frac{4}{9}$
2) $\frac{3}{5} = \frac{3}{5} \cdot 1 = \frac{3}{5} \cdot 100\% =$
$= \frac{3 \cdot 100\%}{5} = \frac{300}{5}\% = 60\%$
$\frac{7}{8} = \frac{7}{8} \cdot 1 = \frac{7}{8} \cdot 100\% =$
$= \frac{7 \cdot 100\%}{8} = \frac{700}{8}\% = 87\frac{1}{2}\%$
$\frac{3}{11} = \frac{3}{11} \cdot 1 = \frac{3}{11} \cdot 100\% =$
$= \frac{3 \cdot 100\%}{11} = \frac{300}{11}\% = 27\frac{3}{11}\%$
$1{,}8 = 1{,}8 \cdot 1 = \frac{9}{5} \cdot 100\% =$
$= \frac{9 \cdot 100\%}{5} = \frac{900}{5}\% = 180\%$
