(2/4-1/7)=10/28
1/(18/28)=28/10
=14/5

Answer 2

$( \frac{1}{3}+ \frac{2}{3}) :( \frac{2}{4} - \frac{1}{7}) = \\ \\ ( \frac{1+2}{3}) :( \frac{14}{28} - \frac{4}{28}) = \\ \\ ( \frac{1+2}{3}) :( \frac{14-4}{28}) = \\ \\ ( \frac{3}{3}) :( \frac{10}{28}) = \\ \\ ( 1) :( \frac{5}{14}) = \boxed{ \frac{14}{5} }$

Espero que te sirva, salu2!!!!
