Answer 1

Respuesta:

Explicación paso a paso:

$a) (1 + \frac{2}{7}) * \frac{2}{3}$ = $\frac{9}{7} *\frac{2}{3}$ = $\frac{18}{21}$ = $\frac{6}{7}$

$b) (\frac{5}{4} *\frac{2}{3} )+(\frac{1}{4} *\frac{4}{3} )$ = $\frac{10}{12} + \frac{4}{12}$ = $\frac{14}{12}$ = $\frac{7}{6}$

$c) \frac{3}{8} -\frac{5}{6} : \frac{4}{3} +\frac{2}{9} *\frac{27}{9}$ = $\frac{3}{8} -\frac{5}{6} *\frac{3}{4} + \frac{54}{81}$ = $\frac{3}{8} - \frac{15}{24} + \frac{54}{81}$ = $\frac{243-405+432}{648}$ = $\frac{270}{648}$ = $\frac{5}{12}$

$d) \frac{3}{5} :(\frac{2}{4} +\frac{5}{4} )-\frac{5}{6}$ = $\frac{3}{5} : \frac{7}{4} -\frac{5}{6}$ = $\frac{3}{5} *\frac{4}{7} -\frac{5}{6}$ = $\frac{12}{35} -\frac{5}{6}$ = $\frac{72-175}{210}$ = $-\frac{103}{210}$
