Step-by-step explanation:
1. [tex] \frac{48}{8} +\frac{44}{8}= 11 \frac{1}{2} [/tex]
[tex]2.\frac{10}{10} + \frac{30}{10} = 4[/tex]
[tex]3.\frac{6}{4} + \frac{2}{3} = 2 \frac{1}{6}[/tex]
[tex]4.\frac{1}{8} + \frac{2}{16} = \frac{1}{4}[/tex]
[tex]5.\frac{4}{4} + \frac{14}{16} = 1 \frac{7}{8}[/tex]
[tex]6.\frac{4}{3} + \frac{2}{9} = 1 \frac{5}{9}[/tex]
[tex]7.\frac{2}{4} + \frac{4}{8} = 1[/tex]
[tex]8.\frac{20}{5} + \frac{15}{5} = 7[/tex]
[tex]9.\frac{2}{4} + \frac{4}{6} = 1 \frac{1}{6}[/tex]
[tex]10.\frac{4}{7} + \frac{6}{21} = \frac{6}{7}[/tex]
[tex]11.\frac{4}{2} + \frac{16}{18} = 2 \frac{8}{9}[/tex]
