Question

а)2/3:(-5/7)
б)-3/4:4/7
в) -7/15:(-2)

Answer 1

Ответ:

$\frac{2}{3} \div ( - \frac{5}{7} ) = - \frac{2}{3 } \times \frac{7}{5} = - \frac{14}{15}$

$- \frac{3}{4} \div \frac{4}{7} = - \frac{3}{4} \times \frac{7}{4} = - \frac{21}{16} = - 1 \ \frac{5}{16}$

$- \frac{7}{15 } \div ( - 2) = \frac{7}{15} \times \frac{1}{2} = \frac{7}{30}$
