TL:
\(\frac{12}{100}\)= 0,12
\(\frac{5}{100}\)= 0,05
\(\frac{306}{1000}\)= 0,306

\(2\frac{3}{5}=\frac{2x5+3}{5}=\frac{10+3}{5}=\frac{13}{5}\)
\(5\frac{4}{9}=\frac{5x9+4}{9}=\frac{45+4}{9}=\frac{49}{9}\)
\(9\frac{3}{8}=\frac{9x8+3}{8}=\frac{72+3}{8}=\frac{75}{8}\)
\(12\frac{7}{10}=\frac{12x10+7}{10}=\frac{120+7}{10}=\frac{127}{10}\)
\(2\frac{3}{5}=\frac{13}{5}\)
\(5\frac{4}{9}=\frac{49}{9}\)
\(9\frac{3}{8}=\frac{75}{8}\)
\(12\frac{7}{10}=\frac{127}{10}\)
a,
\(3\frac{28}{32}=3+\frac{28}{32}=3+\frac{7}{8}=3+0,875=3,875\)
\(7\frac{15}{75}=7+\frac{15}{75}=7+\frac{1}{5}=7+0,2=7,2\)
b,
\(\frac{37}{8}=\frac{8+8+8+8+5}{8}=\frac{8\times4+5}{8}=\frac{8\times4}{8}+\frac{5}{8}=4+\frac{5}{8}=4\frac{5}{8}\)
\(\frac{149}{25}=\frac{100+25+24}{25}=\frac{100}{25}+\frac{25}{25}+\frac{24}{25}=4+1+\frac{24}{25}=5+\frac{24}{25}=5\frac{24}{25}\)
\(\frac{257}{41}=\frac{246+11}{41}=\frac{246}{41}+\frac{11}{41}=6+\frac{11}{41}=6\frac{11}{41}\)
\(\frac{18}{10}=1\frac{4}{5}\)
\(\frac{21}{8}=2\frac{5}{8}\)
\(\frac{100}{9}=11\frac{1}{9}\)

`12/5 =` `2``2/5`
``37/6 =` `6``1/6`
`108/9 =` `12``0/9`
