6/7:4/9=

Answer 1

Respuesta:

a)$-\frac{2}{3}$

b)$-\frac{1}{6}$

c) $\frac{51}{70}$

d)$-\frac{2}{35}$

e)$\frac{27}{14}$

Explicación paso a paso:

$a)$ $\frac{7}{6}-(\frac{9+2}{6})$

$\frac{7}{6}-\frac{11}{6}$

$-\frac{4}{6}$

$-\frac{2}{3}$

$b)$$2*\frac{1}{3}-\frac{5}{6}$

-$\frac{2}{3}-\frac{5}{6}\\\\\frac{4-5}{6} \\\\\frac{1}{6}$

$c)\frac{4}{5}*\frac{2}{7}+\frac{1}{2}$

$\frac{8}{35}+\frac{1}{2}\\\\\frac{16+35}{70} \\ \\\frac{51}{70}$

$d)\frac{9}{5}*\frac{2}{7} -\frac{1}{7}:\frac{1}{4}\\ \\\frac{18}{35}-\frac{1}{7}*\frac{4}{1} \\ \\ \frac{18}{35}-\frac{4}{7}\\\\ \frac{18-20}{35} \\\\ -\frac{2}{35}$

$e)\frac{6}{7} :\frac{4}{9} \\\\\frac{6}{7} *\frac{9}{4} \\\\\frac{54}{28} \\\\\frac{27}{14}$
