(2/3.5/7)+1/2-(4/3:2/9)+(6/7+1/2).1/3

Answer 1

$( \frac{2}{3} \times \frac{5}{7} ) + \frac{1}{2} - ( \frac{4}{3} \div \frac{2}{9} ) + ( \frac{6}{7} + \frac{1}{2} ) \\ \times \frac{1}{3}$

$\frac{10}{21} + \frac{1}{2} - 6 + \frac{19}{14} \times \frac{1}{3}$

$\frac{10}{21} + \frac{1}{2} - 6 + \frac{19}{42}$

$\frac{41}{42} - \frac{271}{42}$

$\frac{ - 230}{42}$

SIMPLIFICANDO

$\frac{ - 115}{21}$
