9)

[tex] \frac{23}{2} [/tex]

11)

[tex] \frac{15}{2} [/tex]

Пошаговое объяснение:

1)

[tex] \frac{1}{2} + \frac{13}{2} = \frac{14}{2} = 7[/tex]

3)

[tex] \frac{2}{7} + \frac{47}{7} = \frac{49}{7} = 7[/tex]

5)

[tex] \frac{11}{12} + \frac{61}{12} = \frac{72}{12} = 6[/tex]

7)

[tex] \frac{7}{12} + \frac{41}{12} = \frac{48}{12} = 4[/tex]

9)

[tex] \frac{1}{2} + \frac{23}{2} = \frac{24}{2} = 12[/tex]

11)

[tex] \frac{1}{2} + \frac{15}{2} = \frac{16}{2} = 8[/tex]
