Answer 2

$\frac{7}{8} \times \frac{5}{9} \div ( \frac{4}{9} - (\frac{1}{6} ) {}^{2} + \frac{2}{3} ) =$

$= \frac{45}{72} \div ( \frac{4}{9} - \frac{1}{36} + \frac{2}{3} ) =$

$= \frac{5}{8} \div ( \frac{16}{36} - \frac{1}{36} + \frac{24}{36} )$

$= \frac{ 5}{8} \div \frac{39}{36}$

$= \frac{5}{8} \times \frac{36}{39}$

$= \frac{5}{8} \times \frac{12}{13}$

$= \frac{5}{2} \times \frac{3}{13}$

$= \frac{15}{26}$

sper că te-am ajutat!
