By what rational number should (-15/6) be divided to get (-5/7)?

$\huge\blue{\fbox{\fbox{\red{\mathcal{Answer}}}}}$

$\frac{( - 15)}{6} \div \frac{( - 5)}{7}$

=$\frac{( - 15)}{6} \times \frac{( - 7)}{5}$

=$\frac{21}{6}$

Answer 2

Answer:

Let the number be x

-15/6 ÷x= -5/7

-15/6 ×1/x=-5/7

1/x= -5/7÷(-15/6)

1/x=-5/7×(-6/15)

1/x=2/7

x=7/2(By reciprocal both the sides.)
