Answer 1

Respuesta:

a)11/14

b)35/16

c)-8/15

d)-44/36  =  -11/9

Explicación paso a paso:

$\frac{5}{7} +\frac{2}{7} = \frac{7}{7} = \frac{14}{14}$         $\frac{14}{14} -\frac{3}{14} = \frac{14-3}{14} =\frac{11}{14}$

$\frac{9}{4} =\frac{18}{8} =\frac{36}{16}$    $\frac{2}{8} = \frac{4}{16}$       $\frac{3}{16} +\frac{36}{16} =\frac{3+36}{16} =\frac{39}{16}-\frac{4}{16} = \frac{39-4}{16} =\frac{35}{16}$

$\frac{9}{5} -\frac{7}{3} =\frac{27-35}{15} =\frac{-8}{15}$

$\frac{7}{9} -\frac{8}{4} =\frac{28-72}{36} =\frac{-44}{36} = \frac{-11}{9}$
