Answer 1

$\frac{5}{9} - \frac{1}{3} = \frac{5}{9} - \frac{3}{9} = \frac{2}{9} \\ \frac{1}{3} - \frac{8}{27} = \frac{9}{27} - \frac{8}{27} = \frac{1}{27} \\ \frac{3}{4} - \frac{4}{7} = \frac{21}{28} - \frac{16}{28} = \frac{5}{28} \\ \frac{7}{10} - \frac{3}{5} = \frac{7}{10} - \frac{6}{10} = \frac{1}{10} = 0.1 \\ \frac{1}{2} - \frac{1}{3} = \frac{3}{6} - \frac{2}{6} = \frac{1}{6} \\ \frac{9}{16} - \frac{11}{24} = \frac{27}{48} - \frac{22}{48} = \frac{5}{48}$
