opera y simplifica ​

Answer 1

Respuesta:

a)6/7 b)5/8 c) 31/78 d)16/9

Explicación paso a paso:

-$(1+\frac{2}{7} ).\frac{2}{3}=\frac{7+2}{7}.\frac{2}{3} =\frac{9}{7}.\frac{2}{3} =\frac{6}{7}$

-$\frac{11}{4} : (5-\frac{3}{5} )=\frac{11}{4} :(\frac{25-3}{5} )=\frac{11}{4} :(\frac{22}{5})=\frac{11}{4} x\frac{5}{22}=\frac{5}{8}$

$\frac{2}{3}-\frac{7}{2} .\frac{1}{13} =\frac{2}{3} -\frac{7}{26} =\frac{52-21}{78} =\frac{31}{78}$

El ultimo sale 16/9 se me borro perdón tamales:
