[tex]2 \frac{3}{4} + \frac{1}{2} = \frac{11}{4 } + \frac{2}{4} = \frac{13}{4} = 3 \frac{1}{4} \\ \\ 2 \frac{3}{4} + 3 \frac{1}{4} = 5 \frac{4}{4} = 6[/tex]
7)
[tex]2 \frac{1}{5} + 3 \frac{3}{10} = \frac{11}{5} + \frac{33}{10} = \\ \frac{22}{10} + \frac{33}{10} = \frac{55}{10} \\ \\ \\8 - \frac{55}{10} = \frac{80 }{10 } - \frac{55}{10} = \frac{25}{10} \\ \\ \frac{55}{10} - \frac{25}{10 } = \frac{30}{10} =3 [/tex]
8)
[tex]1 \frac{1}{4} = \frac{5}{4} \\ \\ \frac{5}{4} + \frac{7}{8} + \frac{7}{12} = \frac{30}{24} + \frac{21}{24} + \frac{14}{24} \\ \\ \frac{65}{24} = 2 \frac{17}{24} [/tex]
