Explicación paso a paso:

1.

$\frac{3}{4} + \frac{2}{5} = \frac{15 + 8}{20} = \frac{23}{20}$

$\frac{8}{10} - \frac{3}{4} = \frac{16 - 15 }{20} = \frac{1}{20}$

$\frac{7}{4} - \frac{1}{2} = \frac{7 - 2}{4} = \frac{5}{4}$

$\frac{5}{2} + \frac{3}{4} = \frac{10 + 3}{4} = \frac{13}{4}$

2.

$\frac{4}{5} - \frac{3}{7} = \frac{13}{35}$

$\frac{8}{6} + \frac{2}{3} = \frac{36}{18}$

3.

$\frac{8}{5} + \frac{3}{7} = \frac{71}{35}$

$\frac{8}{9} - \frac{3}{5} = \frac{13}{45}$
