-3/35 ÷3/5=

(-4/7)(-9/6) ÷-3/5=

(-4/9) ÷(3/9) x (-9/6) ÷(-3/5)=

Answer 1

Respuesta:

$\frac{1}{7} \times \frac{ - 9}{6} = \frac{1 \times ( - 9)}{7 \times 6} = - \frac{9}{42}$

$\frac{ - 3}{35} \div \frac{3}{5} = \frac{ - 3}{35} \times \frac{5}{3} = \frac{( - 3) \times 5}{35 \times 3} = \frac{ - 15}{105} = - \frac{1}{7}$

$\frac{ - 4}{7} \times \frac{ - 9}{6} \div \frac{ - 3}{5} = \frac{( - 4) \times ( - 9)}{7 \times 6} \times \frac{5}{ - 3} = \frac{36}{42} \times \frac{5}{ - 3} \\ \frac{36 \times 5}{42 \times ( - 3)} = \frac{180}{ - 126} = - \frac{10}{7}$

$\frac{ - 4}{9} \div \frac{3}{9} \times \frac{ - 9}{6} \div \frac{ - 3}{5} = \frac{ - 4}{9} \times \frac{9}{3} \times \frac{ - 9}{6} \times \frac{5}{ - 3} = - \frac{10}{3}$
