Answer:
[tex]1.) \frac{4}{8} + \frac{1}{2} \\ = \frac{4 + 4}{8} \\ = \frac{8}{8} \\ = 1 \\ 2.) \frac{5}{6} - \frac{1}{4} \\ = \frac{10 - 3}{12} \\ = \frac{7}{12} \\ [/tex]
[tex]3.)4 - \frac{3}{6} \\ = \frac{24 - 3}{6} \\ = \frac{21}{6} \\ = \frac{7}{2} \\ = 3 \frac{1}{2} [/tex]
[tex]4.) \frac{3}{4} + \frac{1}{3} \\ = \frac{9 + 4}{12} \\ = \frac{13}{12} \\ = 1 \frac{1}{12} [/tex]
[tex]5.) \frac{9}{10} - \frac{2}{5} \\ = \frac{18 - 8}{20} \\ = \frac{10}{20} \\ = \frac{1}{2} [/tex]
hope it helps!
