Question

Alguien que pueda ayudarme con esa simplificación por favor. Gracias.

Answer 1

Simplificar:
1)
$( \frac{2}{7} -3- \frac{1}{6} )+(4 \frac{2}{3} +3 \frac{3}{7} ) = ( \frac{12-126-7}{42} ) + ( \frac{14}{3} + \frac{24}{7} ) = ( -\frac{121}{42} )+( \frac{98+72}{21} )$$= ( -\frac{121}{42} )+( \frac{98+72}{21} )=(- \frac{121}{42} )+( \frac{170}{21} )= \frac{-121+340}{42} = \frac{219}{42} = \frac{73}{14}$$=5 \frac{3}{14}$

2)
$\frac{(2 \frac{4}{5} +5 \frac{3}{5}) }{(1 \frac{2}{3}+2 \frac{2}{7} ) } = \frac{ \frac{14}{5} + \frac{28}{5} }{ \frac{5}{3}+ \frac{16}{7} } = \frac{ \frac{42}{5} }{ \frac{35+48}{21} } = \frac{ \frac{42}{5}}{ \frac{83}{21} } = \frac{42*21}{5*83} = \frac{882}{415} =2 \frac{52}{415}$
