Question

-7/12÷[-2/9]=
2/7×[-6/9]×1/12×[5/4]
[-2/13]÷3/7×[-5/4]
me ayudan :(​

Answer 1

$\frac{ - 7}{12} \div \frac{ - 2}{9 } = \frac{ - 7}{12} \times \frac{9}{ - 2} = \frac{ - 63}{ - 24} = \frac{21}{8}$

$\frac{2}{7} \times \frac{ - 6}{9} \times \frac{1}{2} \times \frac{5}{4} = \frac{ - 60}{504} = - \frac{5}{42}$

$\frac{ - 2}{13} \div \frac{3}{7} \times \frac{ - 5}{4} = \frac{ - 2}{13} \times \frac{7}{3} \times \frac{ - 5}{4} = \frac{35}{78}$
