[tex]a. \: \frac{2}{7} \div \frac{4}{14} = \frac{2}{7} \ \times \frac{14}{4} = \frac{28}{28} = 1 \\ b . \: \frac{4}{1} \div 25\% = \frac{4}{1} \div \frac{25}{100} = \frac{4}{1} \times \frac{100}{25} = \frac{400}{25} = 16 \\ c. \: 0.18 \div 4\% = \frac{18}{100} \div \frac{4}{100} = \frac{18}{100} \ \times \frac{100}{4} = \frac{1800}{400} = \frac{18}{4} = \frac{9}{2} = = 4 \frac{1}{2} \\ d. \: 16\% \div 0.10 = \frac{6}{100} \div \frac{10}{100} = \frac{6}{100} \times \frac{100}{10} = \frac{600}{1000} = \frac{6}{10} = \frac{3}{5} \\ e \: \frac{9}{20 } \div 0.6 = \frac{9}{20} \div \frac{6}{10} = \frac{9}{20} \times \frac{10}{6} = \frac{90}{120} = \frac{9}{12} = \frac{3}{4} [/tex]
