Answer:

[tex]1) \frac{4}{5} - \frac{1}{3} + \frac{2}{9} = \frac{4 \times 9}{45} - \frac{1 \times 15}{45} + \frac{2 \times 5}{45} \\ = \frac{36 - 15 + 10}{45} = \frac{31}{45} \\ \\ \\ 2) \frac{1}{2} - \frac{1}{4} + \frac{1}{8} = \frac{4 \times 1}{8} - \frac{2 \times 1}{8} + \frac{1}{8} \\ \frac{4 - 2 + 1}{8} = \frac{3}{8} [/tex]
