[tex]1.\\- 4 \frac{1}{3} = \frac{13}{3} \\ - 2.25 = \frac{9}{4} \\ \\ \frac{13}{3} \div \frac{9}{4} \\ = \frac{13}{3} \times \frac{4}{9} \\ = \frac{52}{27} \\ = 1 \frac{25}{27} \\ \\ 2.\\- 3 \frac{2}{9} = \frac{29}{9} \\ - 3.2 = \frac{16}{5} \\ \\ \frac{29}{9} \times \frac{16}{5} \\ = \frac{464}{45} \\ = 10 \frac{14}{45} \\ \\ 3.\\ \frac{2}{6} + \frac{3}{4} - \frac{2}{8} \\ = \frac{4 \times 2 + 6 \times 3 - 3 \times 2}{24} \\ = \frac{8 + 18 - 6}{24} \\ = \frac{20}{24}\\=\frac{5}{6}[/tex]
