Answer 1

Explicación paso a paso:

9.

$\frac{7}{8} + \frac{3}{4} = \frac{7 + 6}{8} = \frac{13}{8}$

10.

$\frac{9}{2} + \frac{1}{4} = \frac{18 + 1}{4} = \frac{19}{4}$

11

$\frac{16}{3} + \frac{1}{2} = \frac{32 + 3}{6} = \frac{35}{6}$

12

$8 \frac{1}{4} + 2 \frac{1}{2} = \frac{33}{4} + \frac{5}{4} = \frac{38}{4} = \frac{19}{2}$

13.

$\frac{8}{8} = 1$

14.

$2 \frac{3}{4} + \frac{3}{5} = \frac{11}{4} + \frac{3}{5} = \frac{55 + 12}{20} = \frac{67}{20}$
