Question

Ayuuudaaaaa, el resultado de cada operacion porrfis

Answer 1

Respuesta: $a=-\frac{7}{13}$       $b= \frac{49}{60}$    $c=\frac{1}{2}$     $d=\frac{59}{5}$    $e=\frac{389}{306}$

Explicación paso a paso:

• a= $\frac{6}{13} -(\frac{4}{6} +\frac{1}{3} ) = \frac{6}{13} -1 =- \frac{7}{13}$

• b=  $\frac{7}{6} -\frac{3}{4} +\frac{2}{5} = \frac{5}{12}+ \frac{2}{5} = \frac{49}{60}$

• c=   $\frac{7}{6} -\frac{2}{3} =\frac{1}{2}$

• d=  $\frac{72}{5}-\frac{13}{5} =\frac{59}{5}$

• e=  $\frac{17}{9} -\frac{21}{34} = \frac{(17)(34)-(21)(9)}{(9)(34)} = \frac{578-189}{306} =\frac{389}{306}$
