[tex]3) \frac{4}{5} \times 25\% + 0,2 \div \frac{5}{6} \\ = \frac{4}{5} \times \frac{25}{100} + \frac{2}{10} \div \frac{5}{6} \\ = \frac{4}{5} \times \frac{25}{100} + \frac{2}{10} \times \frac{6}{5} \\ = \frac{100}{500} + \frac{12}{50} \\ = \frac{100}{500} + \frac{120}{500} \\ = \frac{220}{500} \\ = \frac{22}{50} [/tex]
[tex]4) \frac{3}{7} \div \frac{6}{14} + 15\% \times \frac{20}{50} \\ = \frac{3}{7} \times \frac{14}{6} + \frac{15}{100} \times \frac{20}{50} \\ = \frac{42}{42} + \frac{300}{5.000} \\ = \frac{21.000}{21.000} + \frac{12.600}{21.000} \\ = \frac{33.600}{21.000} \\ = \frac{336}{210} \\ = \frac{8}{5} [/tex]
[tex]5) \frac{4}{5} \div \frac{12}{20} + \frac{3}{4} \times \frac{20}{24} \\ = \frac{4}{5} \times \frac{20}{12} + \frac{3}{4} \times \frac{20}{24} \\ = \frac{80}{60} + \frac{60}{96} \\ = \frac{640}{480} + \frac{300}{480} \\ = \frac{940}{480} \\ = \frac{94}{48} \\ = \frac{47}{24} \\ = 1 \frac{23}{24} [/tex]
